You are gonna love the fiber. Good upgrade!
Recommendation depends on the size of your place. If you are gonna keep one device in the center of the house or if your need multiple AP's for coverage. With a single router/ap combo I like the Synology RT6600. Does what you need and easy to manage, configure and update. It includes some software like IDS, VPN, reporting that are useful. Hardware seems solid and OS is stable. Can later add mesh ap's if you want. Don't get caught up in reviews and spec's like wifi7, radio this, that, the other. Stable, secure and reliable are 1-2-3.

If you want to bump it up to Firewall / Mesh AP / POE / Etc Give me a call.
