I would just charge the wet cell as an AGM - very similar parameters anyway. It won’t live as long but it’s not exactly the biggest investment you’ll ever make.
On the AGM, look for one labeled “dual purpose”. These are designed for the life and cycles of a deep discharge but offer near the CCA of a starting battery. Most marine AGMs are dual purpose. The catalog will list both CCA and reserve in Ah.
