I have a FB page specifically for scrappy stuff. I did have a personal one years ago but like you said, it's a pain for switching between the two so I let that one go. Any of my friends and family who still wanted to stay connected followed me over to the scrappy one.
I will say that IG is way easier if you want to easily switch between accounts! I don't have two separate accounts myself but I used to do SSD's IG and my own. There's a single button to toggle easily back and forth.
