This is basically what I wanted to know- if the slightly differently named films were different or not, but,So you have two Kodak b&w films, both of which require the C41 process. The difference is in their names, namely once of them is called Plus.
Your question is, I think : Are there any other differences other than the use of the word "Plus"
I have no answer but hopefully I have clarified the question for others.
If I have done the opposite and muddied the waters further then please respond to avoid the thread straying from its true path

So, I have not found any regular bw boxes but I do have a bwcn and bw+ box, but I don't have them at my place but here's the canistersI can only find the label Kodak Professional BW400CN in a black grey and yellow box. Can you show pictures of both boxes? Thanks

The canisters all say process c41 only on them. You can see it in the shadows of my normal bw, but I didn't orient the plus to show it. I guess the process anywhere on the one ebay box is the indication.Thanks. From what I can see there is nothing on the first two cassettes or the boxes to indicate that these are other than traditional b&w films whereas the BW400CN does mention C41 It just seem strange if these are C41 films that Kodak hasn't indicated this but has done for BW400CN.
I know very little about Kodak's film history but I am tempted to ask if you are sure that the the first two are in fact C41
What I also find surprisingly is why we appear to have no Kodak experts who recall these films and can give definite answers to what seems to be reasonable questions or have chosen not to reply

I have two, frozen 2001 expired 120 TCN rolls and was considering asking about those as well, but that does fit in with your timeline- as one of my 35mm rolls is dated out at 2001, and (strangely) I've got a 2004 expired roll in a tmax 400 canister I don't remember where it came from. and my bwcn 35mm expired in 2008. I read (on wikipedia mind you) that the bwcn replaced the older c41 bw in 2004. Also... what about portra 400bw?There have been indeed two versions (technically) of this chromogenic C41 Kodak BW Film: The first version, introduced in 1998 if I remember correctly, were labelled "T 400 CN" in most major markets.
I have used this film first time in 1999 and got excellent results. Have made some of my "all time favourits" on it.
The box you have showed first - the Kodak Select with "New! Process anywhere" on the box - has a similar design like the T 400 CN. So likeley it is this first version.
Later as a successor, the BW 400 CN was introduced. It was more optimised for making BW prints on RA-4 colour negative paper. Target customers were people who wanted BW prints from their minilabs.
Both films were the most fined grained ISO 400/27° BW films ever produced, even slightly surpassing T-Max 400 (TMY-2) in that regard. But TMY-2 is sharper and has higher resolution.
For you it is quite simple: All films have to be processed in the standard C41 process.
Best regards,
Henning

To expand on Henning's comments:
BW films for Process C-41 was not a big volume or success for any of the film manufacturers. However, it was another product that met a need that could be provided with little cost.

Thank you. That is very interesting to hear from someone involved with the development of a product. I do not remember Portra 400 BW in the US market, but maybe I missed it. The last Kodak C-41 B&W film that I bought was BW 400CN in 135 size. I may have one roll left in the refrigerator. Another note: I think TMax 400 is finer grain, at least in the 135 size, but I never did any direct X-Y comparisons.To expand on Henning's comments:
The next generation was PORTRA 400 BW. One of the advantages of PORTRA Films was that all the PORTRA Films could be printed using the same analysis and printing channels. This allowed labs to handle all PORTRA Films the same no need to segregate films. This was a major driver in making PORTRA Films a huge success for Kodak. PORTRA 400 BW had the same color characteristics as otehr PORTRA Films so it could be analyzed and printed with other PORTRA Films. This allowed prolabs to make monochrome prints on RA-4 paper. From a prolab point of view it provided additional products using existing printers and processes.

I wonder how the sales of Ilford C41 XP2 Plus compares with other trad b&w Ilford films? It always struck me that Ilford regarded XP2 Super as a success
Another note: I think TMax 400 is finer grain, at least in the 135 size, but I never did any direct X-Y comparisons.
Unfortunately, I don't do my own c41 developing. just standard BW.If we assume the same +3/-1 stop latitude that works well with XP2 Super (and many/most other C-41 films), it ought to be a "true" ISO 800. And from what I've read, C-41 films don't age fog as much as silver image films of the same speed -- if you have the ability to process it yourself, it might be worth shooting a short test, unloading in the dark, and cutting the test strip to load and process to see where you stand. You might be pleasantly surprised.
