Welcome! For many years, I used GoDaddy and Hover. But recently I started using NameCheap.
The prices at Namecheap appear very respectable, especially for transfers. The service was great, especially the fact that you can readily send a message to them from their website. The email responses were very quick. And the renewal costs appear to be very competitive. And you don't have to pay for an annual domain discount club membership in order to get those low costs.
Porkbun has also been cited as being low cost, but I can't vouch for them. Ionos appeared to be the low cost, but it turned out that the prices quoted (like $1/yr) involved having to buy a hosting package).
You can do a search on Namepros, and check out the various registrar reviews. Note that Namecheap has frequent sales, including one ending tomorrow, where you can get serious discounts on registrations and transfers.
