You could have it that society’s mostly betas, and you get African wild dog style, like–if betas hang with betas, it’s all normal and they have families and kids. But if an alpha or omega is present in the household–is born, moves in, etc–everybody’s “"cycles”“ shift to give them reproductive priority. You’d have to spend WAY too much time at work and be too invested in it for a coworker to affect you, it’s more of a family dynamic thing; betas might mostly have nuclear families and do fine, in the modern world of beta liberation and reproductive rights rather than fiefdoms, but the Old Fashioned Way would be packs of betas assembling themselves around alphas and omegas. Perhaps in the modern world alphas and omegas would mostly nuclear family it up, too, but their mostly beta children would (stereotype to the point of comedy) just not leave the nest, so most “large families” would spring from a/o pairs, and most only children and small families arise from more common b/b pairs.
Betas might have various more-cryptic reproductive patterns within their a/o centric large family groups, especially when the households passed a certain size, but would generally experience reproductive suppression (but increased life-fulfillment) as parts of these groups. Instead of only pressure to have kids as they got older, betas would be asked about finding a nice other beta to settle down with, sure, but also told leading anecdotes about the a/o pairs in their own family tree, and how their farms and businesses and the children and betas around them are doing.
So being an alpha or omega would make the betas around you keep half an eye on your progress, more obtrusively than it would make other alphas and omegas attentive to you, though it wouldn’t be the same strength of attraction exerted by a/o pairs. The same way humans need to express some reserve towards one another to avoid entanglement, alphas and omegas not ruggedly empire-building would maybe feel pressured to distance themselves a little from most other people (betas). Most betas would, stereotype to the point of comedy, consider themselves immune to their a/o friends (internet friends, etc) in this modern world (esp considering a/o rarity), until actually pressed, at which point they might find themselves to feel more loyal and supportive in That Way after all than they thought. (But it’s a fall in love thing–feelings don’t happen just from proximity, it just can sneak up on people–only household close-proximity reproductive suppression is annoyingly involuntary).
So a/os would play more like an anime style subset of Chosen People Set Apart, in a world by and for the regular people they’re allegedly so distinct from. And alphas and omegas could happily settle down with betas, but without an a/o counterpart they wouldn’t exert the same pheromone dominance over others, and it would be a beta/beta style relationship with no extra pull on the people around them.
Probably these relationships would get routinely bi-erasured, and people would always still be obnoxiously waiting for the a/o person to find an a/o counterpart and start a Real household (that they could send their good beta children to support, etc). A/a and o/o relationships would likewise be (im)politely assumed to be perfectly decent but somehow still just phases, and, even if obviously lifelong, very good and noble but still representing the mild tragedy of not having found their Real counterpart.
In such a world, Real relationships would be beta/beta foremost (as and os representing relationship roadblocks ala sexual infidelity for both parties to avoid entanglement with in order to keep their pairbond prioritized), a/o second but also significantly as a focus of beta attention and energy (who can “fall for” the a/o pair), and beta/ao understood to be the ao partner preferring their beta partner to fulfilling their own aoness (VERY touching and modern and perhaps vaguely metrosexual), and aa oo mostly disbelieved in due to not serving beta interests at all.
