How can I use composite/component inputs on a 4K TV?

I just moved and don't have a TV, and I'm looking to buy a TV that has HDMI, composite, and component inputs so that I can use it for my older game systems as well as my HDMI devices. From what I've seen, TVs in the current market are all 4K and don't have composite or component inputs. I know there are composite/component-to-HDMI converters, but I'm worried about input lag. Does anyone have experience using these? Or am I better off finding a used non-4K TV that has these inputs? 4K is nice, but not necessary for me.

Are you sure? My Sony 900e has component and is from 2017.

Edit: Looks like the 900f has no component.
