This is the method I ended up using.You can use bedrock shears in autonomous activator if you have RoC, they are like fortune 3 on shearing
Also, I used a spider spawner to get wools from string
In the middle I have a betterchest with collector upgrades and light upgrade for the grass to grow at night. Around that I have 4 autonomous activators with bedrock shears. The sheep area is outside with fences going up to the distance the collector will grab the wool. I needed alot of wool quick and had the mats for this method.
