https://oneringmatch.com/ Has a character generator, although I would manually tweak characters. Starting pcs probably want combat proficiency 3 in Moria, for example, and to avoid pcs overlapping too much. To help the pcs feel different I would use both dwarven cultures and use different attribute arrays for each pcs. I’d try to vary the rewards and virtues too, plus invest their previous experience differently.
Official pre generated pcs are here:

But understandably that isn’t a long list of dwarves!
