Congrats on the Baby! I had an XBOX and first bought a switch (which is really kinda bad). When the Switch 2 came out, I decided to give is a shot. It was night and day better than a regular switch, and it can also be connected to a TV, but the resolution and frame rates are no where near the XBOX-S/X or PS5.
I decided to return the switch not only because of that, but because I love stadium creator (which Switch's dont have) and also Playstation came out with Playstation Portal, which allows you to stream games from your PS5 console to the device over your home Wi-Fi or any broadband internet.
Now, its not for travel, I believe you are limited to using it from home, but it does allow you to play away from your TV in your home....
If you are used to PS5 graphics, i'd stick with that and get the PS Portal. WOuld at lease give you a little more flexibilty, while retaining the graphics and game play along with Stadium Creator
