Thanks for the debrief and also for posting those images.
I think that you managed the ‘Dappled Light Subjects’ and the ‘Subjects in Shade and Sunny Backgrounds’ well. These images certainly covey the spirit and fun of the day – that’s obvious. It seems that you learnt a lot doing this: and that’s good.

One suggestion for next time, shooting in Manual Mode - I think that your Shutter Speeds were a bit slow and the Apertures were un-necessarily small for some shots: for example, the Portrait of the Biker sitting down: F/18 @ 1/40s @ ISO 125. I think that 1/40s is nearer the ‘unsafe’ region to get Subject Movement and/or Camera Movement (if the camera does not have stabilization) – and you had a bit of latitude in the Aperture and certainly a lot of latitude in the ISO to bump the Shutter Speed to the 1/200s region.
Shooting under pressure of time or outside one's comfort zone, in M Mode, I have noticed that it is easy for many Photographers to lose their concentration on the SHUTTER SPEED - at least that is very common error with beginner Wedding Photographers: I don't know why but my theory is that most Photographers have predisposition to making sure they have enough DoF and or they shoot in Aperture Priority Mode often and these facts add to them loosing concentration on the Shutter Speed. Anyway just something for you to consider, I'd have a close look at the typical shutter speeds that you were using.

A suggestion about Post Processing that you might consider:
When using a ‘fill light’ or similar option in Post Production, I have the main aim to increase the levels of shadows,
especially the faces and also mid-tone contrast to get some guts back into the whole of main Subject(s), if the main Subject is in shadow against a bright background.
For example the ‘flags shot’. There are many methods. In PS I often use “shadow / highlights" control and I use many small adjustments, typically one 1% or 2%. Also subtle dodging on the face often assists, and finally a slight increase in mid tone contrast and then a slight adjustment in the input black point and grey point, using the levels slider.
Here are two quick sample indicative reworks for your consideration using the above described method, firstly using "shadow/highlights" by eight corrections of only 2% for each increase in the shadow area.
In each sample, the original is on the top and I suggest that you view them at full size:

The Portrait of the Biker is a good shot.
Bravo.
