...new sourcebooks coming next year, but fourth-edition maps kind of butchered the realms and third-edition maps compressed them into a fantasy theme park: i appreciate the proper scale of the fifth-edition map even if broader setting resources mostly entail tracking down older reference material...

...fifth edition does offer officially-sanctioned sourcebooks for the moonshaes, border kingdoms, thay, chult, and icewind dale in addition to the sword coast, though; you just have to delve into the DM's guild for adept and adventurers' league material...

...third-edition maps do alright in a pinch as long as you double the distances...

There's a big one by Mike Schley. Most smaller ones are relatively old or just crops of that one.

There are versions out there but afaik it's super awkward to find them, I'll see if I can find the one I used a couple months ago again and send a link here if I do

Try this one. As the comments of the post say, it's not entirely up to date, but it works well enough.
