Since you are interested in getting a vintage bike, my advice is to ask in the Classic & Vintage sub-forum.

Nothing wrong with asking here, but as you move earlier than the 80’s and 90’s, there...

If you ride a hybrid now without bike shorts and without pain, I think it is more about the saddle setup or the saddle itself.

Probably the first step is to measure that your rear dropouts will accept a 135mm OLD hub.

Next step, as others have suggested, is to make sure your current brakes will work, rim vs disc.

Nope. 650c and 650b are considered the same outside diameter; 650mm. So if 650c is 26” so is 650b.

The b and c refer to the bead diameter; 584mm and 571mm.

650b tires were around before you...

While this is a bit OT, if 26” is 559mm bead diameter and 650b is 584mm bead diameter, that is a difference of 25mm (1”) in diameter.
