If I don't find such a solution I'm perhaps even able to code it myself as an Electrum extension as I know a little bit Python.

If you have those types of skills I assume you're skilled enough to set up a Linux machine with a full core node and your own SPV server. Even if your home network is behind CGNAT you'll be able to connect to it while you're on the go by using tor. I have a set up like that using Romanz Electrs, and it's been running great. Romanz Electrs is super easy to set up and doesn't require a ton of additional recourses. It gives you so many options, it's quite worth the effort and hardware. No trust is required other than trusting the software itself, but that can be verified of course.
