Very useful, thanks for sharing! Was already familiar with fr Spyridon, Heers and Trenham (how can't you be if you're on this forum..) but listened talk 1 of fr Kosmas and I really like it, the intensity, fast paced, stern, ramble kind of style. Looking at the list it's a great variety of topics that fr Kosmas covers. I think for a starting inquirer fr Spyridon is the best, to get into basic characteristics of Christian spiritual life (obedience, love, righteousness etc which he always emphasizes) and get a feeling with the Saints. Fr Heers then offers good podcasts and courses on the basics of Orthodoxy that can feel a bit information dense at the start but are really informative (on his Patreon e.g. courses on ecclesiology, the liturgy, modern Martyrs in the Soviet Union, an evaluation of fr Rose's Orthodox survival course outlying Orthodox history in relation to Western Christianity etc). I've recently discovered fr Trenham's platform at Patristicnectar and I'm really in awe of the quality and quantity of courses there, his catechism course is an absolute blessing. Lots to discover!
