Taken at face value, the short answers to those questions are: Absolutely not, no, and yes.
Sword/Shield were disgracefully bad games, and there are plenty of reasons as to why that is. But perhaps the biggest one is that half the content was carved out of them and re-packaged as a season pass which will cost you half as much again. The games don't actually cost $60 - by the time you're done it's going to be closer to $110, with a constant drain on your resources in the form of Pokemon Home if you have Pokemon to transfer over from old games...which, by the way, you won't be able to do entirely, forcing you to either keep them on your old games or in Home, which is outrageously expensive for what it is. The base games are severely lacking in content, polish, and pretty much anything else, really. Visually they're abysmal for the Nintendo Switch, the online is dreadful - oh, and THAT requires a subscription too, so that'll set you back more money, and believe me when I say you will find no joy in these titles outside of Raid Battles if you don't buy the DLC...which was pretty much what was intended. There is nowhere near enough in the base games to justify the price tag, and what is in the base games is disgustingly poor quality.
...but in all honesty, that's exactly what Pokemon has felt like since Generation V, so if you enjoyed previous Pokemon titles, you're probably not going to notice. Like nobody else seems to, because blinders go over people's eyes when it comes to judging the quality of Pokemon titles. I am of the opinion that we should hold Pokemon games to account for their low quality and that we have every right to expect more for our money, and that they should be compared to similar titles and not solely within the bounds of the series, but I seem to be alone in this for some reason. But if this game didn't have the Pokemon name attached to it, it would be about $15 by now.
Is this any worse than what other games do? No, I could name you several games that are MUCH worse than this. But does that somehow make it more acceptable, or good? Absolutely not. I could point you in the direction of several games with no extra costs that are much more polished, satisfying, and enjoyable experiences than these steaming piles of trash. Don't be fooled into thinking that just because Game Freak did it and it's Pokemon that its OK to be conned out of your money. Especially if you're strapped for cash.
Anywho. That aside, the only reason I can think of to get a Switch over a Switch Lite is to avoid the possible aggravation of stick drift, which is a death sentence for a Switch Lite because you can't just buy a new set of Joycons...well, I suppose you CAN, but it defeats the purpose to have them separate like that, haha. There's nothing wrong with the Lite at all, and it'd play the games you want it to play just fine - although if you were getting higher end games like Witcher III you might find the visuals suffer a bit on the smaller screen for the details - but I would still advise erring on the side of caution and getting a regular Switch, because there isn't really any reason not to unless you're really strapped for cash and dying to get one. You can play on a TV if you want to, if your Joycons screw up you only have to send those in repair and not your entire console - and can buy replacements - and I believe it's fractionally bigger, too.
So yes, to reiterate: Switch good, Pokemon bad.
