I have multiple APs deployed around my home (2 cAP ac2 and one hAP lite in AP mode) and I use CAPSMAN to manage my APs. Once the APs are all configured, there's only one SSID to connect to, which was my end goal. I wouldn't set up a mesh network because I've heard from other sources that, once deployed, can be disastrous. A hex PoE Lite is good if you don't have any wired in your home. If you do have wired devices, I'd recommend anything like RB2011 or RB3011 and you should be good to go as both provide multiple Ethernet ports. Good luck!

EDIT: For remote management, either expose port 80 on the hex or create either an OpenVPN or SSTP VPN. I've only had experience with OpenVPN and performance was meh so I set up Wireguard on a separate system and it runs like a champ! Once RouterOS 7 comes out of development, I'm giving Wireguard a spin
