Need help with choosing AWS EC2 instance type for 7-10 user Tutor deployment

I want to host a LMS for my engineering training material that maybe accessed by 7-10 users at a time.
Planning to use Open edX Tutor on a AWS EC2 instance. Since on a shoestring budget, I am trying to figure out a decent instance that will suffice the above need. After doing some research, I am looking at the following options:
1. T3 or T4g instances (Burstable instances): t3.medium or t4g.medium (2 vCPUs, 4GB RAM)
2. M6g or M5 instances (General purpose): m6g.medium or m5.medium (2 vCPUs, 8GB RAM)
3. Mem optimized instances like r6g.medium (2 vCPUs, 16 GB RAM)

I would appreciate if I can get some suggestions on my choices if they seem reasonable.

Also, if Open edX is compatible with Arm architecture for the T4g and M6g instances.

For 7-10 users which considered small production environment 4 vCPUs is recommended as for memory 8GB is sufficient , however 16GB will give you better performance, the choices you shared all have 2 vCPUs, while I haven’t personally used 2 vCPUs in production, perhaps someone with experience in such setups can share their insights.

Thank you @harout7 !
I suppose I can start with 2 vCPU/8 GB setup and scale up when needed. Because the 4 vCPUs are pricey. Thanks again.
