Will decraesing hose size increase velocity at the sprinkler head?

Or is it dependent on the flow rate of the sprinkler head??

Yes decreasing pipe size increases fluid velocity

Make the pipe something like 1/8-inch diameter and the water goes supersonic

If you have a sprinkler head that puts out 4gpm and a 3/4" hose that supplies 4gpm then decreasing the hose size to 1/2" isn't going to increase the sprinkler velocity.

If you want max pressure at the sprinkler then minimizing pressure loss by enlarging the hose supplying the water is the way to go. Not the reverse.

Now that will only work if the water supply puts out enough pressure right?

If Im dealing with pathetic water pressure I assume downsizing the hose and using the same sprinker will help but just take longer to water. Is this right?

lol. Okay so 3/4 inch hose is always better no matter what. So what about the big 1" industrial hose? With 1" impact sprinklers. Would that be a good all around set up for new lawn installs?

How will shrinking the pipe size increase pressure at the head? The only option you have under the circumstance you describe is the put in a smaller nozzle and minimize pressure loss by overdosing the pipe.
