Here are the mods I recommend. These are all compatible with the latest versions of SMAPI and Stardew Valley on Linux/macOS/Windows. See the player's guide to using mods if you're interested.
I think the best mods are those which improve the game while maintaining its balance, lore, and style.

AutoGate
Gates open automatically when you approach and close behind you. -
Better Sprinklers Plus
Customise the sprinkler radius, with a proportional change to their cost. If you're willing to mine all the ores you'll need, that makes the basic sprinklers useful early in the game and lets you do more than just watering crops every day.
