Right now I have a Prinsu roof rack and I love it. I have 2 load panels on there so its more modular to attach cases or a RTT. I have a Gazelle tent coming in and I'm attaching a solar panel to a power bank with an AC outlet so that I use it for the blow up mattress for the tent. I'm putting on my Cali-Raised light bar this weekend and I'll take a picture of it when I'm done, but that's the best bang for your buck, or go for a Heretic or a Diode Dynamics one.
You can also get an awning for the side. I'm looking into the Front Runners quick detach for their roof awning so I don't have to haul it all the time when I'm driving to work etc.

 

I couldn't find a roof rack I liked so I built my own, going to do an arb sun shade off the side with the enclosed sides to act as a tent. The 2020 may be more solid roof wise, i dont think i would trust the strength of mine to have a cab tent like a jeep or 4runner does. For light bars just find one that fits size wise for what you want ive run amazon and ebay ones and only had one issue that took 6 min to solder. For any light bar upgrade I recommend a heavy duty wireing harness and a relay with a inline fuse.
