i am favor of the old screw in light bulbs, placed any were from 2 to 4 feet apart, and having a line going down one side, and another line of lights going down the other side, and then in middle having 1 or 2 much bighter / costlier lights.
to many times more so in winter turning on lights and needing to wait for (bright costlier center ) lights to warm up before they put out full light. by that time i already found the tool i needed and locking the door behind me. and reason for the cheap screw in light bulbs around the outside edge.
to many times it is just plain "DARK" when i need to work at any side wall were a tool is located or looking through part bins and like, or i am casting a large shadow of myself exactly were i want to look and no way to get around it. and those cheap screw in light bulbs. around the outside edge. reduce and shadows due to coming in from multi angles, and generally if the cheap screw ins are 2 to 4 feet off side of bulding, they end up between me and what i am looking at, vs light bulb being behind me and casting a shadow.
the 1 or 2 much brighter / costlier light in the very center. = wanted simply due to they give out so much extra light vs the cheap screw in. allowing me to see little cracks / hair / pencil marks and like. that i might not see other wise.
============
i am not a fan of florescent lights (tube lights), while they can be nice if you have enough, they take some time to warm up, they can flicker, and they can hum / buzz all day long, and generally requires a ladder and a couple trips up and down it to deal with light cover, removing old bulb, and putting in a new bulb. most of my garage is filled with something making a pain to get a ladder in some place (normally were it needs to be replaced of course) the cheap screws quick and easy, and a few cheap tools on market that you can use to reach up and undo without need of a ladder.
i am just not a fan of the long bulbs, make it led, to florescent bulbs / lights. lots of light in a single spot. but not were you need/want it, when you need/want it. and most likely right in the way hanging down, right were i want to shove something up on a shelf or pull it off a shelf. or i end up nailing the light due to hanging lower with a ladder when moving it around or dealing with lumber.

the cheap screw in lights = 1 to 2 bucks for the plastic piece were light screws in, it also acts as a cover for a metal junction box which you can buy from 50 cents to 1.50 at menards. and light bulbs buy a 10pack for 10. approx 3 to 5 bucks per light. run a string of them down each side for of 40x60 shop = figure 10 to 30 lights per each side, 60 to 300 bucks not counting center lights. think of them as cheap track light / christmas tree string lights but much brighter!

an edited picture i did for someone else, showing some cheap lights, 3 rows (left, center, right) and then a light above the sliding door on the outside of the shed. *shrugs*
