Choosing Pumps for Monoflow Hydronic Heating System

Background information:

I previously posted asking for suggestions on how to split my monoflow-plumbed boiler into more zones here:

I’m getting around to doing the work, and I’m trying to figure out what I should do for pumps.

The big zone currently has a Bell and Gossett Series 100 pump. The plumbing is a ~35 foot run of 1-¼” copper (to the far end of the house) where it splits into two 1” runs, about 60’ long each going around the perimeter of the house back to the boiler. Each of these runs serves 5 convectors (3 on first floor and 2 on second floor) which are fed by ½” piping fishing from the monoflow tees which are at the basement ceiling height.

The zone that was added to the big zone at some point (the room is an addition) is plumbed in ¾” with monoflow tees to two convectors. There is about 70’ of pipe with about 10 elbows in the zone.

The existing basement zone has a Taco 110-338. This zone has ¾” piping and is series plumbed to two convectors in the basement. There is about 120 feet of piping in this zone, and about 12 elbows.

Questions:

1. Is the Grunfos Alpha 15-58F (link https://www.supplyhouse.com/Grundfos-92603115-ALPHA-15-58F-Smart-ECM-High-Efficiency-Circulator-Pump-with-Optimized-Setpoint-Control) a good choice for replacing the Taco 110-338, and for putting on the newly split zone? This pump is attractive to me because it can show head and flow, and the output can be programmed. I cannot find a pump curve for the 110-338 to see if I can run the 15-58F at the same point.
2. Would this same 15-58F be crazy to try out on the big zone too? I know that the B & G Series 100 is a much bigger pump, but I also think that the zone could be over-pumped as is, as my heat calls were not particularly long last winter, and the heat was calling a maximum of 26minutes/hour on the coldest day of the year. I really like the idea of having common pumps that can be programmed. And if one went bad, then a less important zone (the basement) pump could be easily swapped over to the more important zone.
