I had a look at the Meade LX65 6" Mak-Cass you mentioned here, it's a 6" f/12 scope on an alt/az goto mount.

IMHO, this would be a really good system to start on the moon and planets. In order to see the planets well, you really need a long focal length, and the 1800mm you get on this scope will be excellent. Alt/az means that you don't need to spend a lot of time on polar alignment, all you need are a couple of bright stars and you are away! The tracking means that once you are pointing at the planet, it will stay in the field of view for a long time - you might need to nudge it slightly every couple of minutes or so, but it will stay there.
I myself started with a 2nd hand Celestron Evolution 6" (an excellent mount if the budget will stretch that far) and have since upgraded to the 9.25" version (which is easy with this mount, just attach the new tube) and it's great for taking images of the planets and moon, but not so good for DSOs. Check out my page here for what is possible with alt/az mounts and a bit of experience.

Don't forget to check out the used market, you can usually find a bargain there - I bought my scope on eBay, there are a few options right now (if you don't mind travelling and getting a COVID test
).

My first scope was a horrible manual Newtonian reflector which was terrible to use (the AstroMaster 130), but when I upgraded to the Celestron Evolution Goto scope, my enjoyment increased exponentially.
Good luck
