I don't think I want Enterprise to come back, but maybe a show featuring the true birth of the federation and maybe the Romulan War. They could reference Enterprise and the various characters and maybe even get someone to play an older T'Pol.
The Romulan War took place between 2156-2160, https://memory-alpha.fandom.com/wiki/Earth-Romulan_War . It began 2 years after season 4. Season 4 was in 2154.
Jolene Blalock can still play T'Pol.
I agree with a series showing from the formation of the Federation onwards. This series should be around the same year as Star Trek: Picard and Star Trek: Lower Decks, maybe also Star Trek: Strange New Worlds, so we get a series in the distant past of the Federation or pre-Federation and a series set in the future.
I wish they would do an anthology series.
