Generally it’s more considerate to submit smaller batches of (self-contained!) work at a time. Sometimes the work or existing code is so interconnected that this can’t really be done, though. You mentioned spending a month, that’s also a long time in most environments to be off working on bulk changes for later review. A week is probably long enough in most cases, some orgs even prefer to push (if not review) code daily.

Don’t agonize over it though, wanting to improve your impact on others while working is the right direction to point, keep walking that way and you’ll do awesome, let it develop over time. As in, don’t let your desire for politeness slow down your work or growth too much (I do this lol, why I’m mentioning).
