I've been listening to A Delectable Education podcasts and have stumbled across some new curricula that looked interesting. https://www.adelectableeducation.com/
The Peaceful Press

This appears to be a Charlotte Mason-inspired unit study curriculum for 6th grade and under. It covers a variety of subjects that you would typically see in a Charlotte Mason course of study.
Scientific Connections through Inquiry

We are actually going to start this in 2024. I'm buying Level 3. It's a very new science curriculum and all of the levels are not finished yet. It's supposed to be similar to Building Foundations in Scientific Understanding. https://www.bfsucommunity.com/
Beauty and Truth Math

This is a Charlotte Mason math curriculum. Looks interesting. Youtube also has some videos about this curriculum.
