Why not use intellij ultimate? You can easily add all the language plugins (mod clion based ones).
I used to use only IntelliJ until a few years ago a Python feature I wanted was in PyCharm but not IntelliJ. I think it was related to the typing module? I can't quite remember. I've just stuck with PyCharm for python ever since.
edit: But also, I've never had any issue copying my key configs between PyCharm, Rider, IntelliJ.
