DEC2750 purchase advice

[alto]

Hello friends,

I'm looking at getting some new rack mounted hardware, the DEC2750 looks quite nice and is within my price range.
My home (and homelab) use case consists of:

• Running multiple VLANs, some isolated - home LAN, Wireguard network, IoT (isolated)
• Running a multitude of wireless AP's as I'm soon moving to a larger house
• Running a Wireguard server for remote connections into the LAN
• Running Netmaker (in the future, whenever it matures and OPNSense support is implemented)

If the DEC2750 is a poor choice for this, please let me know as I'm looking to place an order within the coming days.
My thinking is that the hardware should be good enough, power efficient, and the purchase would support the OPNSense project somewhat.

Two things I would need some clarification for:

• Can I plug in both an ethernet cable or SFP+ to the DEC2750 for the WAN access? or is it only SFP+ on this unit?
• What hardware should I look at to extend the number of RJ45 ports for connecting devices? I'm not that familiar with the differences between switches and how you usually connect these together with a device like the DEC2750, so any information and advice on this is much appreciated. (mainly considering performance and network isolation capabilities, but I might be overlooking something)
