How can I search to find sound effects like this?

[David Arbor]

Those are very common sound effects that you can get in any library made for motion designers or video editors. Mt. Mograph's Boombox is very popular and lets you add SFX directly in Premiere: https://mtmograph.com/products/boombox

Another fantastic library is from Motion Sound. They have a dedicated app to manage your sounds: https://motionsound.io/

I have not used this so you will need to check to see if what you want is available
