Premiere: None of the sequence presets match my clip settings. What to do?
Those are just presets. Just select one. When you drag a clip into the timeline, Adobe will recognize the clip has different settings that don't match. Just select the option to automatically change the settings for you.

Edit: And you can't magically change smaller resolutions to higher resolutions without suffering some pixelation. Is there a reason you have to upscale to 1080? Devices nowadays automatically adjust to different resolutions. No need to mess with upscaling. Just follow my steps above.
