Solution Architect Associate is what I'd recommend to start with. Practitioner is for non-technical people, Developer Associate and Sysops Associate are just marginally different than SA, often focusing on services which are marginally useful at best (few people use AWS CI/CD solutions and it makes up most of the difference for developer cert), I wouldn't bother with them. I haven't heard anything about the data engineer one (it seems new).
