1.      📌 Where do I store my data in #PowerApps

Depends on the data source and security that you go for.

SharePoint Online for simpler data design and data size.

Next would be Dataverse for Teams with 2 GB for the Microsoft team.

Move to Dataverse for larger data size and security for your environment.

2.      📌How does where I store my data impact what type of app I use?

For the #SharePoint data source, the #Canvas app could be used.

If your data source is #Dataverse or #SQLServer, then premium connectors are required.

3.      📌What type of other decisions go into what type of app do I build?

It depends on your audience. If users are external, then use #Dataverse and #PowerPages.

Use row-level security within #PowerApps.

4.      📌  I’m getting the wrong answers when I search my SharePoint list (it's missing rows). What could be cause that?

The simple reason is delegation. Power Apps to give hard work to the data source and if the data source has limitations such as SharePoint Online in terms of megabytes and bandwidth.

SharePoint is not a database and therefore we get more delegation warnings for SharePoint Online.
