Bug Jar is a lightweight forge modpack focused on cozy farming and small-scale automation, because sometimes you just want to kick back with the villagers and make a fancy garden community.
Vanilla+ without too many crazy mods to bog you down. Simple enough to get into and complex enough to keep you there.

Farming:
Farmers Delight, Farmers Respite, and Pam's Harvestcraft allow for a wide range of crops and additional world gen that can be brought back home and replanted.
Through automation or mass farming, there are tons of new dishes to cook and stock your pantry with!

Insects:
Borgli's Bugs and Buzzier Bees expands on the ambient bees of vanilla Minecraft to include cute little critters to keep as pets or upgrade your farms with.
Many of these bugs have ambient sound as well, which can add a cozy feel to your house as grasshoppers chirp away.

Create:
The new classic of most modern modpacks, Create Mod as well as Little Contraptions greatly expands on what Minecraft could have used copper for.
With all the crops and new recipes, it's probably a good idea to build a fancy farm with all the new machines.

Building:
Woodworks, Clayworks, and Crayfish Furniture complement each other by using JAPPA-style textures to expand your block pallet and give some additional depth.
Many of these blocks work well with create contraptions as well, so you can get some really fancy trains going with these mods.
