He will likely fill his cabinet and other appointed position with loyalists who will do his bidding no matter what. The USSC has given him wide latitude to ignore the law.

That all leads to Trump being able to remain in power after 2028 if he chooses to do so.

I'm curious...how would that work?

I mean, the federal government doesn't run our elections. So it's mid 2027, and various candidates start making preparations for the 2028 elections, and Trump just...announces there won't be an election next year? Is the idea that all the states would just listen to him, and not hold their normal nominating contests for the Presidency? His cabinet and other appointed positions, whether filled with loyalists or not, don't really have a say in whether those primaries happen or not.

Or suppose he doesn't cancel the elections, but says he's going to run again. Are all the states going to let him, in violation of the Constitution? If they did, when the inevitable court challenges come, would the courts - even the SCOTUS - be willing to go along with that? He lost all his court cases last time, and he's not likely to have too many new allies on the bench than in late 2020.

The fact that the states each run their own elections can be incredibly frustrating at times, but it does present obstacles to the President or the Executive trying to run roughshod over the elections process. Trump has a lot of influence with state election officials, and I don't mean to diminish that - but having a cabinet and federal government filled with lackeys doesn't give him control over the elections process the way it would in most other countries.
