Team Xecuter has shown a video of a Switch Lite booting their CFW, using a modchip. They claim to also be able to work with patched switches.
There is no confirmed release date, but they have said "early 2020" and that the first shipment will only be "after Chinese New Year."
So if you're willing to pay for their solution, you could possibly have it in February. Of course, there are no guarantees, they could keep delaying it, or it might just be a hoax. But with both the video as well as leaked pictures of the modchip, there's a pretty good chance it's legit.
If TX does release their solution, you can be sure that other people will try to reverse-engineer it. So I doubt it would be too long before somebody comes out with a DIY, open-source solution using a Trinket M0 or something similar. Question is how long you're willing to wait for that.
In the meantime, I doubt there's any point in trying to maintain a low firmware. I'd go ahead and go online, download and play a few of the free demos available, maybe get a Switch Online membership and play some Fortnite, or buy some of the cheaper indie titles.
