I think you are on the right track for a good support. Unfortunately, the 4 star servants to lack behind 5 star for full support.

Pick from Medea Lily (high party heal and debuff removal), Tristan (group dodge plus enemy buff removal), Helena (group NP charge), St Martha (party debuff removal and enemy buff removal). In a vacuum, St Martha is probably the most helpful for challenging boss fights IMO.
