I used AutoCAD's "Swis721 Lt BT" as my default for years because it uses less ink and is easily readable while using less space than most fonts, but switched to "Arial Narrow" as it's more compact and readable. I use Arial & Arial Bold sparingly on Index sheets. For street signs "Lucida Sans Typewriter" uppercase letters are spot on. Avoid purchasing that cool looking font online that may cause AutoCAD issues later on and will never look the same for anyone outside your office who didn't purchase it as well. Huge assortment of fonts installed with Windows (almost everyone has) that AutoCAD is fully compatible with.

...or use a truetype font for at least the degree symbol. Truetype font characters scale their own "lineweight" based on font size, and not by any CTB/STB settings.
