I am going to ignore the rest of your post and use this specific aspect to highlight something. Joe Biden has had a stutter his entire life. Stutters take an extensive and persistent amount of work to overcome. They are likely to return during times of increased stress, decreased sleep, or when one ages. There is zero evidence that Biden has experienced any kind of mental decline. All the evidence that people point to of him stumbling over his words, calling someone by the wrong title, or whatever other examples you have are almost certainly just symptoms and coping mechanisms used by someone with a stutter.
Stuttering is an unfortunate condition, but it has to do with pronouncing words and problems speaking fluently. I've never heard a stutterer say the sorts of things Biden says.
Which is why I pointed out not just symptoms, but also coping mechanisms. It isn't uncommon for stutters to try to say a word or have a word come to mind and know they can't get it out. That will lead to them searching for a replacement word. This type of self editing is incredibly difficult to do smoothly, especially when you have a camera on you any time you are out in public. It can easily result in the type of fumbling you see from Biden that doesn't come across as stuttering.
