Have you tried StrongBox? It uses standard KeePass vaults and covers the Apple platforms, sync the file with whatever you like and use any KeePass client for Android, Windows, and others. Strongbox is $25/year, but has a trial. If I remember correctly, the Windows and Android clients I chose are both free (of cost). Note: no affiliation with the developer, I just discovered it from a post similar to this, having never heard of it, and thought your needs sounded similar to mine.
