FIBER -- ethernet switch

I am looking to replace my 10+ year old switches
with openBox/offLease/or new equipment.

1.      What 24 port non POE managed ethernet switch with two fiber
        ports do you recommend since I need about 10 switches ?

2.      What is the best way to see what ROUTE my FIBER is actually
        taking to confirm the below layout  (i.e. do TRACERT, etc) ?
1.      Current Fiber Wiring
         a.      siecor optical cable 62.5  / 125 micron
         b.      type DFNR (UL)
         c.      type OFN FT4 (CSA)
         d.      4,300 feet
         e.      I assume multi-mode ?
2.      20MB fiber into Dell SonicWall
3.      switch in building #1
         a.      CAD5e out to employees in building #1
         b.      FIBER out to building #2
4.      switch in building #2
         a.      CAD5e out to employees in building #2
         b.      FIBER out to building #3 (which is behind building #1)
5.      switch in building #3
         a.      CAD5e out to employees in building #3
6.      switch in building #4
         a.      CAD5e out to employees in building #4
         b.      FIBER out to building #5 (which is behind building #4)
7.      etc

Regarding switches...

For example:

CISCO WS-C2960X-24TD-L, 24 10/100/1000 Mbit ports, 2 SFP+ ports, no POE ports.

CISCO WS-C2960X-24PS-L, 24 10/100/1000 Mbit ports, 4 SFP ports, no POE ports.

I would still reconsider models with POE, assuming that you won't replace switches every year, the price difference is not so big as you may think. Maybe you don't need POE ports today or in one year, but what about 2 years, consider especially if you will have to use IP phones...

These are all so called access switches, Layer-2, you have limited Layer 3 functionality but in order to fully use Layer 3 then consider models C3650 which are in different league (also regarding price tag) as are C2960X:

I'd recommend Juniper EX4200, but the Cisco 2960s mentioned by Matt are a solid choice. You'll probably find them cheaper than the 2960s and will do layer2/3.

I don't understand your 2nd question; but traceroute will show you the route a particular connection is taking, yes. You should be able to traceroute from one side of your network and see what devices it takes to get to the other side and how long it takes to do so.
