Do I need a separate app to show my cloud storage as a drive in Finder?
Short answer: Not if you use Storage Studio. Its Cloud Drive shows every connected account — S3-compatible, FTP and SFTP included — in one Finder location, online-only until opened, with edits synced back.
Not if the accounts are connected to Storage Studio. Its Cloud Drive puts every connected account — including S3-compatible storage, FTP and SFTP as well as the consumer cloud drives — into one Storage Studio location in Finder's sidebar. Files are online-only until you open them, and you can edit, rename, move and delete them in Finder with changes synced back.
It's on by default as soon as there's something to show, and the Mounting tab lets you switch it off or choose which accounts and devices appear. Folders shared from your other devices through Bridge appear there too.
A dedicated mounting app may still suit you if you need it without the rest of Storage Studio, or with options Storage Studio doesn't offer. See Cloud accounts.
