I would like to remove the string between ":" and the first "|" using sed.
input:
|abc:1.2.3|def|
output from sed:
|abc|def|
I managed to come up with sed 's|\(:\)[^|]*|\1|', but this sed command does not remove the first character (":"). How can I modify this command to also remove the colon?

You don't need to group : in your pattern and use it in substitution.
You should keep it simple:
s='|abc:1.2.3|def|'
sed 's/:[^|]*//' <<< "$s"
|abc|def|
: matches a colon and [^|]* matches 0 or more non-pipe characters
1st solution: With awk you could try following awk program.
awk 'match($0,/:[^|]*/){print substr($0,1,RSTART-1) substr($0,RSTART+RLENGTH)}' Input_file
Explanation: Using match function of awk, where matching from : to till first occurrence of | here. So what match function does is, whenever a regex is matched in it, it will SET values for its OOTB variables named RSTART and RLENGTH, so based on that we are printing sub-string to neglect matched part and print everything else as per required output in question.
2nd solution: Using FPAT option in GNU awk, try following, written and tested with your shown samples only.
awk -v FPAT=':[^|]*' '{print $1,$2}' Input_file
