Come for answers, stay for best practices. All we're missing is you.

Functional map are always good, to modularize your mappings. There are no performance implications, by adding more functional maps as far as I know.

We do want to evaluate when we need a functional map as they do affect performance and consume resources. Implemented effectively we will minimize the impact.

I normally try to use FMaps only when I have to. I like to keep my output card windows fairly sequential so that I don't have to constantly move to an FMap to figure out what is going on. So that means I may use one or two or even three indexed objects in the main output card rather than calling a FMap. OTOH, sometimes it is a good idea to call an FMap even if there is only a single input if it clarifies the rules and would otherwise clutter up the main map rule window.
