If your idea is to, "find meaning in the molad or its announcement itself,", I think you need to look no further than the fact that we do it.
The point, I think, of these types of exercises, is to emulate the process that was done in the era of the Beith HaMikdash, not to replace what was done, but to make us aware of what is missing in our spiritual lives. At the time of the Beith HaMikdash, there was not necessarily the same emphasis on synagogue participation that there is now, when that's all we have. It is easy to imagine that the existence of the Beith HaMikdash could have been taken for granted. It's in Yerushalayim, you're somewhere in the north or along the coast, or maybe the south, and if you need to bring a Korban you go, if you don't, you don't, until the Regalim.
That's actually why the Regalim were so important - and Shabbath too - to force us to do something as a community and as a nation. Now that everything is so decentralized, it's reversed. We don't have the Beith HaMikdash, so we bring everything we can from it into our daily lives so that we don't lose it. We copy the rituals as best we can, and so we announce the Molad before blessing the new month.
It's easy to ask for blessings; it's something else entirely to copy the ritual that was done when the new month was declared in the Beith HaMikdash. If we're doing the latter, it becomes so much more than just asking for success and health for the month. We are reminding ourselves and putting ourselves into the mood to reflect on what we are missing as we ask HaShem to bless us.
