Most settings of the Gloria don't have refrains; without understanding the context of your question, it would be hard to focus on particular ones. The Gloria as an ancient hymn of the Church has no refrain - its inherent structure does not contemplate a refrain.

Also, even if Glorias have a refrain, the refrain doesn't have to be repeated after the opening iteration. Indeed, the only good rationalizations for Glorias composed with refrains is that the use of the refrain is primarily for the period of time when a congregation is being familiarized with the Gloria setting, and then can simply be dropped like training wheels after that period.

This is one of my favourites: https://drive.google.com/file/d/1pmyY2s3bMQQgZqHOWOfGMlwht-LsmpQx/view?usp=sharing

Use it with the simple mass setting from ICEL. There is a Gloria included here which is good too. An excellent start for any parish.
