I'm a big fan of wilderness maps, being that i live near wilderness myself alone for the last 25 years, i want my stardew map be just like it, i'm not sure how big maps can actually get. I was gutted when i saw the size of the default wilderness map, it hardly deserves the name wilderness if you can't get lost in it.
Farm maps are very much up to your taste, but here's some to check out. I usually just search "Farm" on Nexus https://www.nexusmods.com/stardewvalley/mods/4102 https://www.nexusmods.com/stardewvalley/mods/3888 https://www.nexusmods.com/stardewvalley/mods/3561 These don't replace the Wilderness layout but could easily be edited! And of course, Ace has a huge collection of expanded farm maps! https://www.nexusmods.com/stardewvalley/mods/988 My personal recommendations ^
