See if https://github.com/vinceskahan/raspi-odds-and-ends/blob/master/netmon.sh helps you any for trying to self-heal your wifi. I haven't run it in years since I fixed my home wifi setup by switching to Ubiquiti gear and essentially out-radiating the badly configured neighbors, but it used to work for me. Probably needs a little tweaking for modern Raspbian but it should be self-evident.
I wouldn't run pm2 for what you're trying to do. Maybe supervisord but even that is way overkill. Personally I'd do it in bash called periodically from crontab if you can figure out a way to tell when (if) you need to touch weewx at all.
