They had tons of handy features in Google Maps before it was redesigned using Material Design. We used the route elevation data often to plan hiking trips with our parents to determine if they would be able to make a trek. The map scale was absent from the first couple releases and when they reintroduced it, it would only appear on zoom and then vanish. It took 3 or 4 more releases for them to finally add an option buried in the settings to make it always on.
I'd like to say they did this to present a clean minimalist app but the recent incarnations of it are more cluttered than the pre Material Design version. Sure you can tap on the map to minimize the clutter and then tap again to make it go away completely but tapping also drops a pin if you hold it for a sixteenth of a second longer. And I hope your touchscreen isn't super sensitive because it'll detect that flutter as a double tap and then you're just zooming.
If you'd like to plan trips that have elevation data, I highly recommend komoot.com. It uses OpenStreetMap, and is a great tool for planning hiking or cycling trips.
For any serious trip abroad I use OSMand (but only on Android) ... you can use hiking routes (GPX), all offline (great if you have no phone signal). Also helped me more than once for parking or finding the next public toilet (haha). You can even using for skiing, biking or navigation on the water.
The ability to show photo hotspots on the map and look at the photos was really handy for planning trips to unfamiliar places (or even familiar ones, really), but AFAI can tell it's gone now. Seems it was part of some service they bought, integrated, then killed.
