I don't believe Guardiola would want to change teams. Everything is fine with the Manchester City team at the moment. He is the boss of this team. The players respect him a lot. I'm sure we'll see a few more great seasons. If he goes to another team one day, it could be Barcelona.
I also still really want to see Pep Guardiola train Manchester City and still haven't thought about which team he will go to in the future, because Manchester City is now more suitable for how to train Pep Guardiola so that the team will definitely continue to work with Pep Guardiola in the long term as long as the team can continue to be at a better level in the seasons to come.
Personally I think a good coach or manager like Guordiola should change club for another new challenge to prove his worth as one of the best manager in the world having achieved his aim and objectives at Man City, Barcelona, Bayern Munich though couldn't win UCL with Bayern Munich but with Man City he had won every trophies except the World club cup which I believe he will win in December, there are equally good club in Europe where he can prove his mettle to win UCL trophy, club like PSG is a perfect choice for him because they have the financial resources and capacity with quality players in their yet they couldn't win UCL trophy,
