I am looking for the documentation to determine the meaning of switch port LED indicators, such as solid amber, flashing amber, solid green, and flashing green on a Catalyst 3750X-24P-S switch. I searched for this information on the Cisco documentation website for this switch, but could not find it. There are many documents on this page but I found nothing on this topic. Can anyone help me?

For your model you can look below :
In general - here high level from my notes :
no light - no remote connection or port in shutdown (except for 6500)
solid orange - port in error disable, spanning-tree negotiation, Trunk to access port mismatch or switch may have a faulty port. Port is shutdown for a 6500.
flashing orange - Depending on your switch, 2900/3500 means duplex mismatch error.
flashing green - port working fine.
