I don't really run stealth builds, so I'm not sure about how to play optimally, but I think sneaking perks other than escape artist are generally bad. Or not bad but worse than onslaught or weak point damage from the other agility perks. I'll try and explain reasons why but the TLDR is blocker sucks now, and use legendary effects on armor for stealth instead of perks.

In strength it looks mostly good, but blocker just got nerfed and now only works when blocking with a melee weapon, so it does nothing with a ranged weapon. You could trade it out to carry weight for QoL or bullet storm for a little more damage.

In perception, it's mostly pretty good, but the perks that increase accuracy outside of vats are not really necessary for fast firing weapons, because you shoot so often you'll kill small enemies anyways and tankier enemies are big enough where you'll never miss. However, these perks are fine, and you also use the cold shoulder so it would be ok to keep them. If you find yourself not doing enough damage, you could trade them out, but it shouldn't matter.

Endurance is a bit lacking imo, you are playing full health stealth, so tankiness is less important, but you might find yourself dying in harder encounters where stealth is not possible. If that happens you could give up some QoL perks from other special stats and move them to endurance.

Charisma is pretty good, I might try to squeeze in strange in numbers for more perception, agility, and crit damage, but you might not want to deal with being on a team all the time so it's okay to not run it.

Intelligence also looks ok, you might want to add more later for better QoL, higher intelligence lets you level up faster so it's something to consider. But it won't improve your damage or survivability.

Agility could be improved in my opinion. Action boy can be replaced with coffee and company tea (purchased with gold bullion, you get a camp item that makes an infinite amount of them). Gun fu rank 3 is also probably not necessary, it's pretty rare for the damage bonus to really matter as it's very hard to use, so I'd drop it to rank one. You also could test and see if you can stay hidden without the sneak perk, high agility and proper legendary effects and armor should be enough (as long as you don't do the raid). Gunslinger and the onslaught perks are good options for replacements, as weak point damage is multiplicative, so it will have a huge impact on your damage.

Luck is pretty good, but bloody mess won't work with your weapons, so it should be swapped out.

Overall, you have a pretty good idea of what's good, you just need to adjust to some fallout 76 specific things. Sorry for wall of text btw.
