This really depends on what the app is, how it will be used, and what level of security / infra you want.
How sensitive is the info you're handling, do you need to have ice cold backups from 2019, are you doing analytics / ml on the data, the users, do you have to report on it.
Do you need error tracking? CD/CI? Are you going to spin this out as a service.
In it's purest form, every solution / stack would work nicely. Some heavy, some expensive, most pretty awesome.
The C stack would be the fastest thing on Krypton, but you would need to be superman to build and maintain it.
Rad question.
