Do both, be happy. By doing so, you'll also realize one isn't really an alternative to the other. They're different universes.
That's right... you can enlarge onto any size ortho film then contact that to another to make a large negative. You can employ dodging/burning and control contrast somewhat by choice of developer...The other option is to make fully analogue enlarged negs using the standard 2-step process.
8x10 Cons:
-Film has to be developed to a specific contrast index that is different than what I normally shoot. These negatives will likely be unsuitable for silver gelatin contact prints and shooting the 8x10 would be used specifically for making alternative process prints.
Both is an eventual possibly, but my wallet short term would be more unhappy.
That's actually a good idea especially if you have access to affordable film for this purpose. In the US, it's still possible to obtain affordable x-ray film and perhaps even ortho litho film. These products are also available in Europe, but they've become cost-prohibitive unless you're really dedicated to the craft and have rather deep pockets.The other option is to make fully analogue enlarged negs using the standard 2-step process.
That works well if your target alt. process isn't too outlandish in terms of its contrast requirements. I understand from your post that Weese makes Pt/Pd prints, and the contrast range for such prints is close to what you can work with in VC silver gelatin as well. OP mentions salted paper and New Cyanotype; both 'like' negatives with a tonal scale of 2.2logD or beyond (in UV). Even with pyro negatives (and I've done, still do, a ton of those), the distance between what comfortably prints at grade 1 or 0 on VC silver gel and what you need for a salt print is just too big. You end up with a compromise in either or both directions. BTDT. There are ways to stretch the compromise a bit - for instance by using only short wavelengths for UV printing, which is now possible with LED. But even so, you'll be working with negatives that do not necessarily hit the nicest tonality that VC paper has to offer, or you fall short in 'oomph' on the alt. process side.Carl Weese worked out an approach to pyro development to create "switch-hitting" negatives that can print well either on silver variable-contrast paper or in alt processes.

The 8x10 camera route will be more expensive all-in than an Epson inkjet
I don't know if they come with a full set of inks.
ortho lithography film.
what would I be missing out on if I go with an older Epson 3880 vs newer p900. At least as piezography and digital negatives are concerned it looks about the same?
I think the P900 features smaller minimal droplet size, which should theoretically translate into potentially smoother negatives. Yeah...theoretically + potentially...I couldn't say if the difference is very noticeable in reality. What magic you pull with curve creation and QuadTone Rip probably will always have far more impact.
I didn't suggest this <ortho lithography film> specifically because I've been told it's "impossible" to get the density range and tonality you'd want --
Not necessarily as resolution depends on the dot pitch in the head as well as the step size of the paper. Although smaller pitches and step sizes also at some point require smaller droplet sizes in order to effectively realize higher resolution. Droplet size mostly determines density range through dot size, so tonal resolution. Simply put, more shades of tone. Inkjet is kind of an oddball technology in terms of resolution and tone since it's effectively a hybrid of a screen printing and continuous tone system.I assume smaller droplet size corresponds to higher max resolution/PPI for the prints?
