My main problem with Fritzing has always been the amount of pain to add new parts. I prefer the look of Fritzing to other applications when technical cartoons are best suited as the means of communication. In the end I found it took less time to build a bunch of shapes in things like Visio that looked close enough.
I can't say I've ever tried the PCB tool enough to have an opinion because the experience stopped when the Library didn't have a workable part ready to use.

As for the edge lit display we see every day, I see an automotive instrument cluster pretty much daily. The needles on the gauges in even very recent cars are still edge lit.

Which thickness is this material? The data sheet lists values in the range of 0.02" to 0.10". Thanks!

If I was a new maker, I would start by getting a Molex Universal Crimper, $55 or less, and an assortment of Molex SL series connectors. From experience, I would advise folks to stay away from connectors more than 8 circuits wide because of high insertion and removal forces. It is not much of a limitation for makers as, 2 rows of 8 is 16 circuits which is a lot of circuits going to just one place. The Pins and Sockets are reasonable and pretty well stocked by the usual suspects. As a bonus, the contacts are compatible with 0.1 header so they can be used to make custom male and female jumpers in a pinch. There is a large variety of shells of every shape and size mate wires to wires, wires to boards, and wires to panels.
Personally, my tool box has Deutsch DTM and DT series connectors, Anderson Power pole in the 75 Amp and smaller body style, Sub-D connectors with 9, 15, and 25 circuits, and a large assortment of PIDG terminations especially the ring terminals.
I keep Deutsch DTM and DT Series connectors on hand for working on my vehicle. They are a great combination of affordable, easy to work with, and rugged. They also offer some premium options such as macined pins and sockets for higher current applications. Recently I've found a number of 4-way and 8-way indent crimpers at the sub-$50 price point that do a good job of crimping the machined contacts.
I use Anderson power pole for weather protected higher current DC applications. These can be had in a kit 20 or so connectors and a crimp tool for less than $100.
Sub-D connectors can be had for very cheap. All of the usual suspects stock parts, though I've found several small retailers keep a better stock at lower cost in small quantities. It is easy to find variants that are weatherproof and you can be reasonably sure that it will mate with the pieces you have knocking around in the used parts bin.
One last thought. I hated connectors until I spent several years in industry. My time in industry taught me that what I hated was bad connections. I learned how to prepare a crimp, and that my 50 cent garage sale crimping pliers did not produce a proper crimp. Ever since getting a good but not exorbitant crimper, I'm very happy with my connections.
