#Moon Druid might be your best option

The feature of all Druids, irrespective of their archetype, is their ability to gain a "shield" of hp through their wild shape forms. Because Moon Druids are incentivized to shapeshift a lot, and they gain access to very powerful wild shape forms, being able to at-will shapeshift into a high hp creature (with some decent attacks to accompany them) will be very beneficial in keeping you alive. You'll also gain access to some powerful spellcasting abilities, and your high Wisdom score will complement those abilities.

At level 6, you are limited to CR2 Beasts. So you could shapeshift into, say, a Saber-toothed Tiger, gaining 52 hitpoints. Or you could shapeshift into a Giant Constrictor Snake, gaining 60 hit points. You have a lot of ways to substantially improve your survivability by simply relying on the extra hitpoints provided by these kinds of forms, and combined with your ability to also regenerate hitpoints either through Cure Wounds or your Combat Wild Shape feature, you'll offset the lost Constitution by a tremendous factor.

Another consideration is the fact that while shapeshifted, you only retain your mental stats (Intelligence, Wisdom, Charisma), whereas your other stats are replaced by the form you choose. So in a wild shape form, your lack of Constitution might as well not exist.

There are limitations of course: if you ever fall out of those forms, you'll be vulnerable. But that would be a problem regardless, and I think this shores up your weakness in a reliable manner.

#Consider Lizardfolk to further bolster survivability

Irrespective of whether you go Moon Druid or not, gaining the extra +2CON is a good way to at least recover some of those lost maximum hitpoints, and since it also provides a +1 to Wisdom, it'll at least complement your class choice.
