A "free" option if you have some PC hardware lying around is to run OPNsense/pfSense instead of buying a dedicated box. I say "free" since it will use more power and require more time to configure and manage.
Alternnatively, I ran one of TP-Links AX consumer router/AP combos for several years and it was solid. Even had an OpenVPN server built in. I can look up the exact model if you're interested.
Look at Mikrotik. Very affordable and extremely powerful. Only do this though if you know what you are doing with networking
If you had a pc already with two NICs, you could do sophos xg home on it or a pfsense/opnsense. I’m planning on virtualizing a VM on a cheap mini ryzen box that meets that (ace magician makes one for $300).
What do you want to do? How fast is your internet? 1Gbps fibre requires something much beefier than 50Mbps.
How many servers do you have going? Are people accessing them from outside?
How many people in your household? Are they gamers and need low latency? Heavy streamers? Working from home needing VPNs?
Without this context just look at a pricelist.
I am looking for a device that can keep up with a gigabit connection
I've been very happy with Ubiquity Edgerouters the last few years. Their ER-X model can do 1Gbps total... So if you're downloading at 500Mbps then you can upload at 500Mbps. It come in about USD 60 I think.
Next level up is the Edgerouter Lite 3. It is much beefier and can easily handle 1Gbps both ways and even faster. It's just under $100. 99 or so. Maybe you can find it on special.
They are really prosumer and definitely much stabler than typical consumer routers. Eg I haven't reset mine in more than 2 years.
It's not open source like mikrotik but they are very hacker and tech use friendly. Most things work via CLI. And most advanced router functions are supported.
I wouldn't recommend the ER-X, it's absurdly slow. Also far too many config items don't exist in the webui and are CLI only.
More than a few, but here's a few I'd recommend in that price range (NOTE: Not beginner friendly)
Mikrotik Router only, no AP - $95
Best option by far is a PC with Opnsense installed on it.
Do you need the latest router, or just "a" router? I usually get mine for like $10 at Goodwill. They're a couple years old when I get them, but they work fine and I don't need anything fancy.
Do those have any memory (storage and ram) to run a secure, up to date firmware, like openwrt?
My guess would be it depends on the device
