Seeking recommendations for move to AWS from dedicated server hosting about 20 domains

I'm looking at the possibility of moving to AWS from a Centos 7 dedicated server that I've been using for many years. There are roughly 20 domains, many which have little traffic. 2/3 of the domains are wordpress based and some others Laravel or straight php/html. There are a couple of static sites as well. I've attached the domain bandwidth/storage/db/email account info below as an image. The biggest site sees about 350 GB bandwidth per month peak, and 2.2 gig of storage. The largest in terms of storage is about 10 GB. Some of the domains use mysql for WP, laravel, php etc. Some have no databases. Some of the accounts also have a number of email accounts and one site currently only functions as an email server. During some peak times, about 15-20 days per year, mysql can max out the server's resources and bog the entire server down.

I'm considering the following:

• A Lightsail instance for each domain (however even that seems like overkill for the low bandwidth static sites). An advantage is each site has its own IP.
• Sharing multiple low resource intensive domains on one Lightsail instance
• Hosting the more resource intensive sites on their own lightsail.
• Setting up shared hosting for all websites on an EC2 (would need recommendations in terms of using RDS or not, etc).
• Setting up shared hosting for most low bandwidth websites on Lightsail or an EC2 and the more resource hungry sites on their own EC2.

I appreciate any advice.
