To Map or not to Map?

Hey guys, long time GM here entrenched in prep for an upcoming short campaign. I've always run games using online tabletops, this campaign will be using foundry vtt. I've always made a lot of maps for my games. Not just battle maps but maps for... well everything. Every shop, inn, shack, road side. Everywhere any kind of interaction happens between players and NPCs.

I'm aware there is a certain amount of taste involved in this but I'm also wondering if this is a bit of a crutch for me and maybe there would be benefits to using a more theatre of the mind approach to non combat interactions. I'm interested to hear your thoughts / experiences on the subject. Can you have too many maps? How do you decide what to map and what not to map?
