I have assisted recently in purchasing hardware for a small home 2.5GbE and Wi-Fi 7 capable network, it's really simple with 4 devices only from Ubiquiti - 2x UX7
* + 2x USW-Flex-2.5G-8. No PoE, uses 4x included USB-C power adapters.
ISP -> UX7 (Gateway, Controller, Access Point) + USW-Flex-2.5G-8 <- Ethernet
** -> USW-Flex-2.5G-8 + UX7 (Access Point)
This thing can do 2.3Gbps WAN + IDS and has 14x available 2.5GbE ports (7x at each end). Super small size, power efficient, wife approved, total cost $716 as per Ubiquiti Store US (plus some Ethernet cables purchased additionally). Coverage - it's in a townhouse around 2500sqft total, second UX7 is upstairs on a diaginal somewhat, around 40 wireless devices on different bands, all happy.
Mesh-scalable, super-compact 10G Cloud Gateway with integrated WiFi 7.

Flexible, 8-port 2.5 GbE switch with a 10 GbE RJ45/SFP+ combination uplink port that can be powered with a USB-C or PoE+ adapter.

* - I was a bit sceptical about this one being new Wi-Fi 7 product, but it works well. No issues with installation and tuning, no one called me back to ask questions. The network has 4x VLANs set for LAN and WLAN for usual Guest, IoT and they wanted restricted NAS to specific devices, but it was done by the owner and I don't know details. Simple home network and inexpensive.
** - don't remember if the link between the switches was 10GbE or 2.5GbE, sorry. Can ask if very important.
