I’ve tried many times for a few years now to get this working. Even though I get platformio to create a compile_commands.json it still doesn’t work very well. Thinks std::string is a uint_8 and so on. I’ve just given up on it and use VS Code to program the ESPs I work with. Use neovim for everything else.

Just bought a Mikrotik LHGG kit for LTE internet and went from about 3-5 Mbit/s down with a TP-link (archer 400 something) to 30-150mbit/s down and much more stable. I’m really impressed with it and WinBox and will for sure have a good look at their switches when it comes to putting up the home network infrastructure. Though, as you said, you need to know what you are doing and need a better understanding of networking but it also gives you a better flexibility and more things that are possible to do.
