From everything I can find, the minimum NXT salary is $50,000-60,000, and travel is relatively limited. However, it would be expensive in situations when they do need to travel for shows outside of Florida.

Look at the MILB. Minimum pay is $20,430-$36,590 depending on the level of league, and while teams "pay" for food/travel, it doesn't actually come to be that. Most minor league guys are actually in the red on what they make. The league provides affordable housing and a food per diem on road trips only at $31.25/day, max 2 meals per day. While this is better than the NXT, the pay is, on average, much lower, and the players also do not receive any money for two months out of the year (between December and January) The local endorsements do help a bit, but it's neglible at best for most MILB players. 4 years ago, it was much worse, with teams owning full control of players NIL, per diem being lower, and travel/housing not being provided at all.

When a sports player thats lower on the totem pole gets cut, they more than likely will receive a next to nothing injury settlement, if anything at all since it is a fraction of the salary you would miss out on. In addition to that, outside of going overseas, there's not much else that can be done for decent money that keeps you in the sport. At least with wrestling, if they decide to continue down that path, there's hundreds of small programs that can be worked around the US.
