You inherently want to be looking for apps targeting the very latest API level. So targetsdk 36.
Why target newer SDKs?
Every new Android version introduces changes that bring security and performance improvements and enhance the Android user experience. Some of these changes only apply to apps that explicitly declare support through their targetSdkVersion manifest attribute (also known as the target API level).
Configuring your app to target a recent API level ensures that users can benefit from these improvements, while your app can still run on older Android versions. Targeting a recent API level also allows your app to take advantage of the platform's latest features to delight your users.
Older apps targeting lower levels results in having apps wanting to access legacy permissions such as all your media instead of just accessing folders and data it creates and/or not using the system file picker etc for example.
This is a benefit to using Play Store as your app source because these levels are enforced. Getting your apps elsewhere means you as the user need to be more conscientious of this by checking it yourself and deciding on the risk and how best to manage it if you do choose to use it, such as isolating them in a secondary user etc.
Usually when apps aren't targeting a higher API level it can be a sign that the application is no longer being maintained or supported too.
