I made a post a few days ago asking your opinion on Manjaro and it was very mixed, with a slightly negative overall opinion. I heard some recommend EndeavourOS instead and did some online research and it seems to be pretty solid and not have the repository problem that Manjaro has.
Just for context I am a Linux noob and have only used Mint for about the past six months. While I don't have any major complaints, I am looking to explore more distros and the Arch repository with its rolling releases. I am not a huge fan of how certain packages on apt are a few years old and outdated. However, I also don't have the time to be always configuring my OS and just want something that works well out of the box.
If you want something that "just works" any Arch base won't be a good idea in my opinion. I love Arch but there will be certain things to figure out from time to time and for someone with little experience they can be tough! For you usecase I would recommend Fedora, that's a lot more up to date but not a rolling realease and tends to just work for me.
