pretty sure you should actually know the answer to that by now. if, for some reason, you dont (which is unlikely), SE seems to reward incompetence and doesnt expect skill, even at end game. unless you are doing it intentionally, its highly unlikely.

Hmmm. Banned no. You should never have a problem with normals, or any of the standard/casual content you mention.
I suppose people could add you to their personal black list, but that can't keep you out of a Duty Finder instance they are in.
It could mean they use that blacklist as black book of people they don't want to be in a high end PF with. But to take exception to someone because of how they are in a normal content they'd have to be extreme. Kind of looney extreme. And they'd be doing you a favour, you don't want to be in a PF they are in, and they would be a minority so small it's not going to impact you.
If anyone says that in XIV chat log though, do everyone a favour and report them for harassment.
I doubt it will make a difference on its own, but if they are a dickhead a lot, they'll get reported a lot, and when they finally step too far out of line, I'd like to think they will get less benefit if the doubt.

well these days i do have problems with normal group content because of 7.0 graphics that makes seeing bosses AoE attacks quite hard in many boss fights and then there is times when i'm simply too focused doing my DPS rotation that i forget to keep eye on combat it self and mostly ended up dying on either boss AoE attacks or on the boss mechanic.

Players who black list me to avoid be in endgame content with me then they don't have anything to fear about me be with them when i haven't done any endgame content since 2014 because back in 2014 i tried to do The Coils of Bahamut raids but i never able to complete The Binding Coil of Bahamut - Turn 5 and since then i haven't tried to do any endgame content when i know that i will never able to complete them.
And since 2014 i haven't used party finder to join party or recruit party members for endgame content either.

I'm really sorry to hear that. If I was still subbed, then being in EU I'd try and persuade you to join me to try the 'current' unreal and to prog some extreme. If you put a blind group, no guide, it really is quite fun. Unfortunately you need to be in it for the fun prog and the clear. Because if you are in it for fun + rewards your plumb out of luck.
(That means joining farm parties with people who are staring down 50 clears, and then things start to get a bit more intolerant and a lot less fun.)

Because breaks don't exist.

Yeah sure, but there's breaks and there's living under a rock.
