How to tell them apart
The core contrast is whether your list is complete or just a sample. と presents an exhaustive list — everything named is everything involved, so ステーキはナイフとフォークで食べる means knife and fork and nothing else. や signals a non-exhaustive list, implying other unmentioned items exist, so ビールやワインを飲んだ means beer, wine, and similar drinks. Swapping them is unnatural: using と when you mean や falsely claims the list is complete, and using や for a fixed pair like ナイフとフォーク sounds vague when the set is exact.
- と Use と when you want to list items exhaustively, implying nothing else is involved.
- や Use や when listing items as a sample, implying other similar things exist.

| や ya | Connects nouns as and, or; marks a non-exhaustive list | N5 |
と to
Links nouns together (and); shows doing something alongside someone (with)
The particle と connects two nouns, listing them together like "and" (お子様セットとクリームソーダ), and also marks the person or thing someone does something with, like "with" (彼女と友達になる). It simply follows a noun in both uses.

Obviously that's different for men and women.
-
自分と気があわない、いけ好かない、人がいるとします。
Suppose there's some jerk you just can't get on with.
や ya
Connects nouns as and, or; marks a non-exhaustive list
The particle や lists nouns non-exhaustively, meaning the items given are examples and others exist, as in 本や雑誌. It attaches directly to nouns and is more casual than と. It can also appear in set phrases like 〜ていいや expressing mild acceptance.
