If you want to walk, as opposed to just get somewhere in a car, I have yet to find anything better than an OS map. Google Maps is hopeless for footpaths; OpenStreetMaps is a bit better but it depends a lot on whether somebody enthusiastic has put in the data for the area you're in. The OS map is always reliably comprehensive. Plus these days if you buy a paper map it includes a code so you can also download the digital version to a mobile app (or you can get an annual subscription to get access to the whole lot, but for me I find that uneconomical.)
In Czechia and Slovakia we have mapy.cz which gives you more detailed map for walking/hiking, including contour lines. See [^1] for example.
The coloured trails you can see at more detailed zoom levels, are part of the hiking trail system. The outdoor signage even has a national technical norm [^2] (in Slovak, but has some terminology translated int to English and German).
This is just OpenStreetMap with another frontend on top, you can see this by going to the area[1] and going to the right, selecting layers and looking at the CyclOSM one.
Also, a bit lame that on mapy.cz, you have to click on the "and others" to actually see the OpenStreetMap credit.
Surely there's nothing wrong with using OSM as one of your primary map data sources? As far as I know, Mapy.cz uses several sources in the Czechoslovak territory, although abroad, perhaps quite a bit fewer of them are being used.
It sees where you are, finds incomplete items on OSM and asks you if you know things about them. Very handy to use as you're walking around, and a very easy way to submit data to OSM.
I, personally, gave up trying to update the data for my area, because about once a month all changes get reverted as "they may be from a copyrighted source" (which happens to be the public domain federal mapping service).
Someone else was more persistent, and managed to get my suburb as existing after five years.
There's a lot more to it than just nobody having volunteered to do the legwork yet.
You cannot just copy and paste things from a public domain data source without first checking the copyright terms and making sure that they're compatible with the OSM license (if they are, you can comment on the revert changeset saying so):
In my experience, the satellite imagery available in the OSM editor to trace buildings and paths (which the other commenter was talking about) - and when I want to add shops and other things; a quick survey with some photos - are both more than enough for most things.

There's an oxymoron here. Many public data sources that are free to use, do in fact have copyright considerations to be made, correct.
However, "public domain" does not have copyright terms attached. That is why it is in the public domain. If something is actually public domain, there is no copyright holder, and no terms to be enforced.
There's now a £2.99 a month subscription, which can be cancelled at any time, that gets you all maps - and you can download chunks in advance too: https://shop.ordnancesurvey.co.uk/apps/os-maps/
I've found open street map much better in the lake district. The car park at walna scar is missing on the os map, which is the best spot to walk the old man. There are a number of missing paths on the os map around rusland pool.
You're not kidding about the limited coverage -- their website shows nothing except some trail maps over the whole of southern England with the exception of Dartmoor. And southern England is where I am so it's where I walk mostly...
