Bike fit for a newbie

Hello! I purchased this bike, a 2015 Ghost Panamao X3, a little over a year ago. I rode it a fit times after I bought it, put it in the garage, and didn't take it back out until this July when I started commuting to university. When I bought this bike I don't recall the store staff (I bought the bike at Mountain Equipment Co-Op, which is a very reputable store) ever mentioning anything about whether or not the bike was the right size for me, but i did have a friend with me who has 30 or 40 years of pretty serious biking under his belt and he thought it looked fine. I guess right now my main concerns are:

-Saddle height
-Saddle fore/aft
-Overall fit

I did notice that I looked rather upright and hunched over, but that's due to me trying to hold the remote control for my camera in one hand and awkwardly holding myself up with my other foot. The bike is sized as a medium (530mm frame size, 590mm top tube length). For reference I am about 6' with roughly a 34" inseam with my shoes off. Regarding riding style I'd say I'm a pretty casual rider, but I'm not looking for a bike that rides really upright, but I'm also not looking for something that rides too much like a road bike (that probably isn't too helpful). This bike is also definitely not meant for any serious off-road biking. About the extent of that would be some easy dirt and gravel trails. Please let me know what you think, as well as any adjustments you think should be done. Currently my saddle can be moved back another 3/8" or so before it's maxed out. Also for reference, the stem on there is 75mm long. All specs for the bike (including for other frame sizes) can be found at GHOST BIKES: Panamao X 3.

looks like a pretty good fit to me.
Arched back is not hunched over - it's using your core muscles for support, and is the way we're supposed to ride to avoid discomfort and injury
Main thing, keep your wrists straight and elbows bent - don't lean on the bars, use them for balance. If you can't do this with the reach you have, adjust the reach.

Saddle height and for/aft is about your knees and pedal position.
You want to be able to lock your knees, but you don't want to have to lock your knees to complete a pedal stroke; you don't want to have to lean side to side to complete your pedal stroke. Fore/aft is all about riding position - the more upright you ride, the farther back and lower the saddle should be.

I believe the upper back is not supposed be rounded the way yours is. I think it should basically look like it looks when one stands up straight and relaxed. I think that's achieved on a bike by rolling one's pelvis forward so one's hands reach the bars naturally, without stretching. I believe anything else stresses the back in ways it shouldn't be stressed.

If you've got too much weight on your hands, it could be a fit issue, but it could be fitness. If you search the web for 'core strength indicators', you should be able to find ways to test your core. If your core is strong and you put too much weight on your hands, your problem is more likely to be fit. If your core tests less than strong, your problem is more likely to be fitness.

The bike looks OK for normal use but it is a little short for you. At the 9 o'clock position of the crank, the bony part under the knee just under patellar tendon looks to be directly over the pedal axle. So you can afford to slide your saddle back a few cm to get some more cockpit room. If you do this, you may need to lower the saddle about 2cm too to keep the same knee angle at the bottom. If you combine that with possibly a 10mm-20mm longer stem, it'll help you flatten your upper back in a more athletic position. Being less crunched will also help your lower back.
