it depends what you need it. If you want a "stupid" tube station for local traffic, then you want unmanaged. It needs less power. If you instead want to have multiple VLANs, which are separate virtual networks inside your network, you need managed. Then from the GUI you say "port 8-12 are for VLAN 5 which is 10.0.0.1/8 and does not have internet access, rest is normal LAN". If then the switch has lots of fast ports, then it needs lots of power to manage the communication, more power means more hot, and more fans.
So can't a router do the VLAN stuff?
Your question exposes a language problem.
A router cannot do that. A router connects two networks together and routs traffic between them. That is it.
A home “router” is a combination device that includes a router, a wireless access point, maybe a modem, a managed switch, a dhcp server, a firewall, and more.
If you need a managed switch with more than 4 ports… you buy a managed switch. It is simple.
I feel like routers are overhyped.
An L3 switch is a router. Though most of them don’t have enough resources to take a full BGP routing table, at wire speed.
