Personally I just want a direct follow up to Picard. I enjoy the TOS era but in terms of live action I think the TNG/DS9 era gets too little focus since VOY ended, even with Picard. I want to see the 80s/90s races (Bajorans, Cardassians, Changelings, Trill, Ferengi, Bolians, etc.) get some more live action focus and doing a follow up would be a good place for that. I'd take that over spinning off Discovery, even though S4 was the best season so far.
