Okay, one thing that would help us help you in this case is that when picture speaks a thousand words, a video speaks a million words. Having a recording of the event would help us get the best idea on what’s going on to help you. But based on the information you provided, I can think of something that comes to my mind.
a) Approaches too far right of the runway can mean several things. What airport and which runway are you approaching? You’ve been flying simulators for years so I assumed you know about offset localiser? I’m wondering if you’re approaching an airport runway with an offset localiser which tends to point your aircraft to either side of the runway.
b) Floats over the runway can mean several reasons, either you didn’t arm the spoilers, or you didn’t manually deploy the spoilers, or that you’re approaching too fast and too hard which resulted in the bounce or floats. Again without a recording on what happened, it’s difficult for me to imagine the situation.
c) Pitching up and stop following G/S could mean a few thing too, it could be AI copilot taking over, or your phantom inputs coming from your controls overriding things, or something wrong with your trimming.
You may have been flying flight simulators for years, but out of all those years, have you been flying the A320 long?
In the end, try to do a bit of housekeeping:
- Set flight model to modern, don’t use legacy.
- Set assists to hard/true to life (you already done this, but doesn’t hurt to recheck to make sure).
- AI Copilot need to be turned off at all times.
- Set deadzones to all your controls with at least 5-10%.
But out of all this, it may not apply to your scenario at all. So, a recording of what happened will help greatly. As a bonus, here’s a recording of me doing the landing. I don’t seem to get the issues you’re having. And I 'm using the Experimental Custom FBW version.
