Just a quick note that Nebula Genomics is not among the defunct. They were acquired in August 2021 by ProPhase Labs, but service was never interrupted.
Relatedly, it might also be worthwhile explaining somewhere that whole genome sequencing results from companies like Nebula, Dante Labs, or FGC can be submitted to YFull for analysis, which would then return both SNP and STR evaluations. It may take a little work to make certain that STR data is correctly transferred to MitoYDNA because the YFull naming schema differs slightly from that of FTDNA, but the info would be there.
Edited to add: Should have mentioned that Full Genomes Corp (FGC) offers as a $50 option Y-SNP and Y-STR reports. I've never used them, so I can't comment about what the reports contain. But they may include the usual FTDNA-like marker count numbers.
