Yes, uranium is theoretically finite, but only now known reserves is enough for something like 100'000 years on current level of power production of whole planet (not current power production of existing nuclear power plants, but total power production as-if it is made only by nuclear plants). And it is not all reserves for sure, and in 100'000 years, I hope, fusion power plants will be reality
With regard to space needed: imagine if every existing building had roof top solar panels. We’d get quite far. I think we have the space for a few wind turbines to get us the final few kWh.
