I use Tubi as well. I use Chromecast for YouTube, Tubi, Pluto Hoopla, Kanopy and Prime. Easier to use their apps. My bedroom TV is no longer supported by Netflix so I use it for watching Netflix on that set. I got it because the pad or my phone is controller so dont have another remote. Cheap to $39.
Hoopla and Kanopy are provided by public libraries
My previous TV has a Roku stock (earlier gen) that works fine, but drags ass sometimes. I thought about getting the highest-end Roku for about $100, but instead I got a larger TV with newer Roku built in, and for a little over $200. :^)
