Now would be a good time to look for a .com you like, or one of the more common TLDs. And register it at Namecheap, Porkbun, or Cloudflare. (Cloudflare is cheapest but all-eggs-in-one-basket is a concern for some.)
Sadly, all the cheap or fun TLDs have a habit of being blocked wholesale, either because the cheap ones are overused by bad actors or because corporate IT just blacklists “abnormal” TLDs (or only whitelists the old ones?) because it’s “easy security”.
Notably, XYZ also does that 1.111B initiative, selling numbered domains for 99¢, further feeding the affordability for bad actors and justifying a flat out sinkhole of the entire TLD.
I got a three character XYZ to use as a personal link shortener. Half the people I used it with said it was blocked at school or work. My longer COM poses no issue.
