Is להקשיב synonymous with לשים לב? I keep writing "pay attention" when I see הקשב - an imperative I heard a lot in Hebrew school years ago
Not really, it means listen.
Sometimes הקשב can mean pay attention, or just attention in a military context, but לשים לב is more like to notice, it's different.
Hakshev¹ li ²kshe-ani medaber!
¹ Imperative, 2nd person (you), masculine, singular: (to a man) listen. See the chart @ https://www.pealim.com/dict/1961-lehakshiv/

Aw, but it's so much more fun not to!
Don't you use that tone with me missy, I'm not asking, I'm telling. Oh, talking to you is like talking to a brick wall. Well, if you want to act like a child, i'll treat you like one.
When you have kids, I hope they're just like you!
is this said for a man?
