I have been considering if I should be getting a Nintendo Switch, and would like to hear what can I expect from this gaming console?

A little of my gaming history. I never have been a console gamer. I never owned any playstation/xbox console in my life. The only one I ever owned probably is the NES classic from 30 years ago  growing up playing games like super mario bros n tetris.
Ever since then, I have been a PC gamer, starting with Diablo, Starcraft, Halflife, Skyrim, Counter strike etc. Now I am only a casual gamer, occasionally playing some game like GTAV, COD, CS GO. But because my job nature requires me to work from my pc computer/laptop long hours, I found myself staying away from computer whenever I am OFF from work. Therefore I no longer do any serious gaming on computer, even though my pc hardware easily can support the latest triple As games.

My wife is currently pregnant and I am planning to spend more time with her in the living room, instead of separate myself in my home office. The idea of getting a living room gaming console cross my mind recently. Even though I may be gaming, but being physically there by her side should be better than not being there. She will be playing with her phone & swiping insta/fb/game anyway. She will nag me, if I play pc game in my office room... online competitive game like CSGO can never be played with her around. She will constantly come and kacau me until I get killed and given up totally .

When considering gaming console, the only thing that comes to my mind is PS4. I think because of the more serious type of games available. I believe I am a more "visual" kind of guy, and good graphic always catch my attention first. I really wish to play games like The Last of Us, and Red Dead Redemption with amazing graphic on my tv. But after few days of careful consideration, I realised maybe that is just what I Think I want. Maybe it is not such a good idea to be so focus on such serious game, even when I am with my wife in the living room. Maybe is not a good idea to play such gore, and violent games on a big living room tv, with a pregnant lady . She is quite timid when comes to these 

Yesterday my wife mentioning bout those classic super mario games, pacman (probably the only games she ever played), which she is quite fond of (which girls dont like cute characters?). She asked me if "is there any more super mario game nowadays?", which I explained to her Mario is a game/character that is Nintendo exclusive. That trigger something in me, reminding me of the latest console by Nintendo Switch released 2 years ago... with very interesting playing options. I went ahead to look for all the reviews of this console and try to understand as much as I can. I feel the concept is more family orientated (not sure bout it in actual execution)

Part of me wants to try PS4 (more serious gaming), but part of me feels Nintendo Switch could be a less "selfish" choice (more casual, wife can join and play occasionally, she may even enjoy watching all the cute graphic). I could be wrong, maybe I am at age stage where I couldnt be a serious gamer anymore.

I will to hear comments & advice if I should go for Nintendo, especially coming from people who have owned both the nintendo & ps4 or even pc. Will I be bored and regret with Nintendo limited games choices? I understand a good game doesnt necessary comes from the best graphic, but good graphic simply make people want to play the game in the first place these days. I feel games from Nintendo are those which you won't find it interesting, until you start playing it, and you are hooked. Good example like mobile CandyCrush  , it doesn't attract me at all. I only start playing to try out why everyone is crazy about this game. Then I find myself spending long hours playing it. Maybe I find myself too old/lazy to learn new complicated games.. aiks.

What do you guys say? Should I join the Switch Community?
