My company has decided to move away from G Suite to reduce costs, so I'm in charge of providing alternatives.
They are accustomed to using Gmail, and don't handle many emails per days (probably around 50 emails received and 50 sent, in 4 mail accounts).
As I don't have much experience with setting up server emails, I thought of setting up an email like Amazon SES, and setup an email client like Thunderbird of configure their Gmail accounts to send and receive via Amazon SES.
For what I read Amazon SES is more used in apps, to mass mail. But maybe it can be used as standard mail anyway.
Is there a downside to this? Is there something that will change that I should mention them?
Note that Amazon WorkMail is not an option, since they carry around the same cost than G Suite.

SES is not designed for this - SES is primarily for automated sending email, with the facility to receive email and send it to automated systems via Lambda, SNS, or stored on S3. Sending would actually work fine from email clients. The thing that won't work is receiving email, as below - it doesn't store it for collection by IMAP or similar.
You should consider FastMail and Zoho as well, both are cheaper than the big three and provide a quality service. As Michael points out Amazon Workmail is designed to do what you need, but at a price similar to the big three.
If you can't afford a reliable hosted email service then you're probably going to have to host your own email server. This comes with complications, primarily around spam. You'll have to factor in setup costs, hardware or VPS (an AWS t2 nano or micro would probably be fine), configuration, maintenance, and support. I suspect that unless your company is fairly large the costs will be similar to using a hosted email service.
