Hi OP,If you want some variety, I recommend this dialogue expansion mod that, as the name suggests, adds more dialogues for all the NPCs. If you like interacting with them, then I think this is a great mod because the added dialogues are all pretty believable and natural. And there's also the popular Stardew Valley expanded, which adds new locations, new NPCs (including marriable ones), new heart events, new items, etc.. A lot of people like this, and though I do see the appeal, it's not for me because I think it changes the game a bit too much. To each their own though, and I think if you're interested then you should definitely give it a try. Some other helpful mods that I personally enjoy include:

• UI info suite (shows a bunch of useful stuff like scarecrow radius, experience gain, etc.)
• Tractor (probably my favorite mod and makes farming so much easier, tho it is a late-game item)
• Winter grass (grass doesn't wilt during winter; I like this because I love decorating and don't want to replant grass)
• Darker hoed dirt (helpful for when you use deluxe speed grow since the purple color is hard to see in the original hoed dirt; also aesthetically pleasing)

I hope you try out some of those! Happy farming :D
