Might be one of these https://littleprinceplants.com...
Never had one of these but have had other echeveria types. Wouldn't dare to give general care tips for the plant as some are different than others. I just know that the majority of mine weren't hardy outside in 8b zone. I don't keep succulents indoors as I have no bright light. I would imagine that like most echeveria, they require at least bright light to help maintain their compact rosette shape.
Yes, there are hybrids of filiferum, and it may be one of them. I don't know these plants well enough to say which is which. The care would be the same.
