Organic maps
It's not overly complicated, doesn't eat up data, has offline mode and works well for both driving and cycling. Oh and it's FOSS, community driven, no data collecting.
Organic maps as a map works quite well. Its routing leaves much to be desired for cycling though.
https://github.com/organicmaps/organicmaps/issues/1518 would help with that.
I mostly use OsmAnd for everything.
Also https://www.opencyclemap.org/ is nice if you want to find bicycle paths.
Another nice tool is https://www.komoot.com as it has a lot of features for planning (longer) trips by foot or bike.
I also like BRouter - e.g. https://brouter.m11n.de . There other versions of this with different settings and languages.
I think all of them are based on OSM data, but they augment them in various ways.
I live in Chicago. You don't need maps here.
