Howdy! You’ve described a very broad array of things you would be interested in, so I’ll list vehicles I have personal experience with as well as one for each that I don’t have, most people think are fun/good. You’ve said you’re interested in WW2 era stuff so I’ll also try to keep these around that ERA/BR range. I’m also going to skip nations or individual TT’s if I haven’t played them, but you shouldn’t exclude them when you choose; I just haven’t time or money to grind them yet.
