Classical Music Newbie - Trip to Vienna

Need some help - not traditionally a classical music listener, but will be in Vienna in October and I'm really interested in experiencing something it'd be hard to find elsewhere. When in Rome, right?

After some searching here, it sounds like the Philharmonic Orchestra may be a great way to do this, but I'm having trouble choosing tickets - I've attached an image of the options in my possible price bracket. Some questions:

1. Is this particular concert the best choice if only visiting one while on a short visit?
2. Is there anything that stands out there seat wise?
3. Is there a reason Cercle is so reasonable considering it appears to be front and centre in front of the stage? I'm assuming the asterisk is the reason why, but can't see any other info - maybe members tickets only or similar.

Any help at all appreciated - here's a link to the evening I'm looking at if that's easier to see - https://shop.musikverein.at/selection/event/seat?perfId=10229285544209
