Which tools simple database with front end?

I want a simple form input to create records, then an edit view, save and archive. Also to be able to chare records with people within my org.

So far I have looked at Sharepoint list with Groups and then a powerapps front end, but have also looked at Forms with Sharepoint List behind it which can add records fien but can you view edit and share records like that?

There will only be less than 250 records so its not a big complex database, mainly text fields but also attachments. 

Any advice on which O365 tools I should investigate?
