I think self-guided and virtual leasing will be more quickly felt but for longer term impact I feel the 'less in person supplier selling' has a higher chance of moving the needle (assuming it holds that way because sellers gonna sell). Why? Because without a bi-weekly or monthly barrage of vendors supplying the staff with candy/treats, guilt, and other coercions the prop staff is left with making purchase decisions on a need and value basis alone. Most items sold to multi family that relies on these sales routes and bombardment is a commodity item (such as flooring). I was a multi year rep & sales manager and we could track down the the month when a rep was hitting the routes and 'servicing' the properties. Visit the props properly and on schedule and the calls/orders come in because if you aren't then A) your competition else is, or B) your product is of low value anyway and without you to push it's purchase they wouldn't buy it. So without the cajoling fewer things that don't need to be purchased anyway might not get purchased (saving $) OR the staff might honestly consider what's the best value if there's not that personal pressure to "use Donna because she's nice" even though her prices are higher (saving $). All that being said I don't think the reps will stay away unless you force them...sellers gonna sell.
