What is your opinion on canister filters (or any other type; UGFs are rarely used nowadays)?

Those filters are really good for 40-55G tanks. I have a few of those.I'm very happy with my marineland emperor 400 HOB. Lots of space for your own media, pretty quiet, and 400 GPH. All that for just $50!
I love mine, get about a years worth of time between cleaningsToo expensive, too much maintenance, too much replacing filter media! Hamburg Mat Filter Is my favourite. With proper stocking you never have to clean it. I've seen HMF filters that have been running for over 8 years without ever being removed from the tank. You can also use them as a vertical surface to grow plants, and grow plants riparium style on top of them
