I was looking for a more lightweight FOSS map app (as opposed to OsmAnd+, which is excellent but not the most performant), as far as I can tell the Maps maintainer had a falling out with / didn't respond to the F-Droid maintainers.
That said I had to piece this together from some commit messages by the F-droid maintainers so I'd prefer a better source myself.
I recently tried the newer iOS app and it requested my location in the background somewhere around once per minute when I wasn't using the app. Didn't do anything to investigate— I just deleted the app— but it was sketchy.
I've been using Maps, from fdroid, also. It is very good, quick, and you can choose tracking on and off, etc. It states under info, that it is based on maps.me, version that's working is 9.1.8-8.
I'd be interested in something more FOSSy, myself.
