Is this Leshen homebrew race balanced?

Question

The Leshen are a race of plant-like fey, born from places over flowing with druidic magic. It is said that when the elves came to the Material Plane from the Feywild, they planted a sacred grove for their wild god. Ages later, the grove still stands, but the elves are long gone from those lands, now enveloped by demonic power. A bastion of purity at the edge of the demonic wastes, the sacred trees birthed a race of vigilant protectors, clearing a portion of the corruption. In time the race spread, though its rarity remained. Leshen are iron-willed and zealous in their guard of nature, they often oppose more civilized races encroaching on wild lands. Leshen appear as Humanoid creatures, with bones of wood and skins of thorny, tough plant material. The race uses the general post Tasha's Cauldron of Everything template.

Answer 1

This is slightly weak

I'll use detect balance here. It works well if there are no strong synergies between abilities, and if the abilities are close to the standard racial ones, which is the case here. It recommends a total score of 25, and a range of 24-27.

Ability Score Increase is standard +12

Speed, Size are standard +0.

Creature Type non-humanoid +2

Vigil I'll treat this as Advantage on a Situational roll. There are quite a lot of undead, fiends and aberarrations, so knowing about them can be valuable and will come up occasionally. The tracking, probably less so. (If you think this is only a rare roll, it only would only be +1.) +2

Symbiosis One cantrip is worth 2, a level one spell from 3rd is another 2. Neither of the two spells is known for being overpowered or useless (although Infestation is a weak damage cantrip), so the standard values should serve fine. +4

Sylvan Talents Choice of a skill proficiency is worth +3

Total: 22-23 points

Even giving some features the benefit of doubt, this is below the recommended range, so it probably is a bit too weak. It could use one more thematic feature worth at least 2-3 points, for example a level 2 spell at 5th level, the ability to speak with small beasts, 13+Dex natural armor, mimicry, mask of the wild or similar.

Answer 2

That seems balanced to me, nothing sticks out as being problematic. This seems like a solid basis for a control character, or a good druid stand-in with more flavor.
