So i've been in contact with the firm that provided us most of the computer hardware for the lab. Translated to english, they sugested this:
Try to stay away from 1/10G hardware and invest in Mulit-Gigibit switches, a lot of new consumer grade hardware will come with 2.5G or 5G network adapters, with the Ubiquiti 10gb switches (16XG with RJ45 10G converters) they will drop down to 1G because the SFP+ switches don't support 2.5 and/or 5G.
Since you're network is managed localy and there is no need for cloud acces management we would go for a high quality business router, 1 unmanneged or basic managed multi-gigabit switch and 1 unmanneged or basic managed gigabit switch. All with 10 gigabit SFP+ or copper uplink options. We suggest following setup:
DrayTek Vigor 3910 10gigabit compatible router (price point around €800)
This router lets you load balance on either 10 Gigabit SFP+ (not in your case) 2x 2.5 Gigabit copper or 4x 1 Gigabit copper. You can use 1 SFP+ port as the backbone output for your switches and then the setup is very flexible you can, at this point load balance the 4 existing 1 gigabit lines and when they upgrade you can either go wit 10 gigabit with the SFP+ 10G WAN or even load balance 2x 2.5 gigabit over the existing cables with a switch upgrade.
NOTE: according to them this is the only one that thicks all the boxes i asked for since the UDM Pro doesn't support load balancing at this point. They also suggest not mixing ubiquiti with other hardware, go full ubiquiti or go something else was the suggestion.
For switches I see 2 possible combinations:
Option 1: (price point around €900)
Netgear XS512EM or XS712T Multi-Gigabit switch with dual SFP+ uplink
This switch gives is the best bang-for-the-buck at this point for multi gigabit switching. You get a 10 gigabit uplink to the Vigor Router over SFP+ and appart from the 3 workstations with 10 gigabit ethernet i would rout 6 to the wall sockets in the lab and leave one as spare. This is far more future proof.

Netgear MS510TXPP
This switch can be daisy chained from the XS512 to provide you with 8 POE ports, (4x Gigabit, 2x 2.5G, 2x 5G), You can use the existing acces points on the gigabit POE ports but if you ever upgrade to acces points that can handle 2.5G or 5G this switch can handle it.
Option 2: (price point around €900)
Netgear S3300-28-POE
This switch allows you to connect all wall-sockets and acces points to the 1 gigabit side of the switch with a 10 gigabit SFP+ uplink to the vigor router. It gives you a lot more ports then the previous setup.
+
Netgear XS505M
You can daisy chain this switch to the S3300-28 through the SFP+ interface. It gives you enough input/output for the 3 workstations and one spare.
All this comes around 200-300 Euro's over budget but they suggest going up to around € 2000 to and just go with the full multi-gigabit network to ensure the network is ready for the following 5-10 Years without the need for further upgrades.
NOTE:
They distribute Cisco, Draytek, Netgear, Microtik and TP link but price/quality wise suggest Netgear fits this setup. They suggest to stay away from microtik for this case because of the lack of some functions in the GUI.
What do you think of this setup?
Thanks in Advance!
