I have Flexicolor and Ektacolor unopened chemicals (concentrates) that are by 6 months. Any opinion on whether it would be worthwhile to use them? I would use them fairly quickly, the Flexicolor probably within a week or two and the Ektacolor probably within 6 weeks.

The Ektacolor chemicals are, of course, for prints.
If they don't perform satisfactorily, you are out some time and a few sheets of paper - not great, but not a disaster.
I would try using them.

The main concern would be the flexicolor developer concentrate that contains the CD4. It's either the A or the C bottle, I'm not sure in which one Kodak puts it. If possible, compare the color of that concentrate with fresh concentrate to see if there's a difference. There's shouldn't be much of a difference.

They should be fine, they keep as concentrates for at least a year with no problem. Agreed re: check the color against what you know it should be. Kodak publishes what the colors should be in their tech papers on the products.

If it is Flexicolor Developer it must be Kodak. If so then it is the part C that contains the CD-4. Check the color of the liquid in the bottle. The bottle may be a brown glass bottle but you can see if the liquid is still transparent. If it has gone bad it will be dark brown or even black as supposed to be see through transparent. If you don't plan to use it soon don't open the cap of the bottle. Once opened it will go bad in a month or two. If it has gone bad the part A and B will be good still for years.
