Other posters already covered it but yeah, in standard tuning string thickness might give you a very slight, barely detectable difference if any at all. Thicker strings only matter when you’re playing in alternate tunings, and even then you have to tune quite aways down before regular strings hit their limit and become too floppy to use.
Outside of that? Strings aren’t meant to last forever! Try several different types and find what you like!
@jennifilm Isn’t Thunderbird open source? It worked well enough for the bit I used it ages ago.
