I feel this is what I’d like to see. Not really sure where else they could take it either:

Rey rebuilds the Jedi, their “home-base” is the islands of Anch-To
Luke’s force ghost, (alongside Yoda, Anakin and Obi-Wan) offer knowledge and training to Rey and other students. VERY fan service-y, but it would appease the diehards that think Rey is not “good enough”
Finn is a Jedi
Poe has settled down from the war, maybe some type of injury, and assists Rey and Finn with their new Jedi Academy. Helping to pass down his military knowledge learned from Leia, Chewie and Lando.
There is no-longer a galaxy-spanning government. Each planet has its own government established by its people and maybe there is some form of Union or Treaty adhering to basic human rights, etc.
The Jedi are now actually the “guardians of peace” and travel to more dangerous planets to help topple tyrannical governments and gangs and restore freedom to the citizens.
The big bads of this movie (or trilogy) would be the crime lords and underworld scum. I really think this is where George was going with bringing Maul back, but to make it different, I think something other than a darksider or Sith would be needed.
EDIT: forgot to include… Older Grogu is involved somehow.
