Marble Falls, Fredericksburg, and Kerrville are all nice and within 1-2 hours of Austin or San Antonio. Johnson City, Blanco, and Burnet are nice as well, but they are all smaller (if that matters).
If I had to pick from all of those, I’d pick Marble Falls because of the gorgeous views...
Lot of rich people in Marble Falls, they literally have garages at their homes for their jets.
I try to get to Fredericksburg every chance I get, I may retire there.
Nice vineyards for wine tastings, and some of the best German restaurants in the country.
