These settings are purposely limited to save performance, but you can change them yourself to both increase view distance and quality of dynamic shadows. You can also type up to 10 (maybe more, not sure, but 10 has been enough for me) into the field for number of Cascaded Shadow Maps (in the settings for your directional light). The slider only goes to 4, but if you type it, you can override that setting.
I have also had very good results playing with the following settings:
(Not sure exactly what this does to be honest, but it affects the distance at which shadows are visible. Lower numbers give higher visibility at distance. Default is 0.03)
(affects how small a shadow needs to be on screen before starting to fade out. Default is 64. Lower value gives longer view distance)
(affects how small a shadow needs to be on screen before disappearing. Default is 32. Lower value gives longer view distance)
(affects the resolution of the shadow on screen. Default is 1.27324. Higher value means higher resolution)
These settings can be set in engine/config.ini. Be aware that these settings affect performance, so if you want maximum FPS they might not be optimal, but for prerendered stuff (I primarily make prerendered archviz videos) they work great. Also, the numbers I have used might be a bit overkill for your project, experiment a bit with them to find the sweet spot for your project.
