I do a few things:
1, all of my consoles, streaming dongles, anything else I want to hook up, all go to a surround receiver with multiple HDMI inputs, and a single HDMI output to my TV. This makes a lot of sense for me because I have my consoles and the receiver on a tall cabinet next to my TV stand, so I'd rather not have a half dozen cables flowing across to reach the TV from there. In lieu of a pricey AV receiver, you could also just use a cheaper HDMI switch
2, a lot of trial and error with routing cables in a way that takes up as much of the slack as possible so I don't have to coil the excess, and also buying shorter and/or slimline cables so that there is just physically less that I have to cable manage
3, velcro. velcro, velcro, velcro. Double sided, with hook on one side and loop on the other, so it can be used as cable ties. There's a bunch of different widths available, but in the end I'm always looking for the big rolls that I can cut to length rather than the pre-cut ones that have a hole in one end so you can cinch down on it. Like this:

I used to work in IT and now work in datacenter operations, and I've developed a bit of a knack for cable manglement over the years
