This probably illustrates my disconnect from reality, but I’ve never understood why a company would care about share price once they’ve left the door. I get that the co still owns its own shares and can conjure new ones for sale, but why would those very infrequent events interfere with the day-to-day operations. In my (wrong) eyes, it’s like pro-baseball players trying to increase the value of their trading cards via their participation in the game. The team doesn’t matter any more, it’s al about what the card owner wants.
Company itself really shouldn't. Everyone involved in management from board to executives do. Board operates behest of stock owners, executives operate behest of board. Such to keep their job they have to do what stock owners want. And stock owners either want dividends or growth in some term.

These are often both weak signals, though. They'll govern very high level decisions, but all the day to day is inside the company. Just as I want a return on the money in my bank account (as I was promised) investors want a return on their money too, and as you say, the executives and board should care about making sure the people who put money into the company are getting a decent deal out of the arrangement.
People have always way overstated the power and scope of “fiduciary duty.” It doesn’t mean you have to redline your company at all times to maximize every single penny in the short term at the expense of all other considerations. That’s just a cultural thing we do in the US by choice
Selling more stock is usually a lever a company can pull when they want. So even if a normal company in normal times doesn't have a reason to do so often, they can if circumstances change. Tesla and some other meme stocks have been extremely aggressive about selling more shares into crazy valuations, and have raised immense amounts of money doing so.
Plus as others have said, usually all of the decision makers have a bunch of stock exposure and will prioritize their own financial gains over pretty much anything else.
