As most people know, Intel have lost the plot and are behind AMD on everything CPU and GPU related (with the tiny exception of the N100 series CPUs from Intel which are perfect for low power and even fanless applications). As such, their CPUs are mostly bought by organisations updating previous environments with like for like replacements for whatever reason (like vSphere's EVC which allows you to run newer processors from the same manufacturer as if they were an older model, and enable hot migration between CPU architectures and thus minimum disruption on hardware refreshes). Pretty much everyone else is getting the better and cheaper (per processing power) AMD CPUs.
Intel NICs are pretty good overall (the X710 which spent a year+ with broken drivers causing silent network failures/downright crashes while still being in the hardware compatibility list of VMware and other "enterprise" vendors notwithstanding), and they're getting more popular for consumer devices too. An Intel CPU on a non-low cost PC/laptop almost always means an Intel NIC (WiFi and/or Ethernet).
For many organisations buying servers, Supermicro* is probably their best option. They're cheaper, have much higher flexibility in terms of form factors, chassis, components, number of whatever slots and mostly reliable. However their support is less reliable than the theoretical Dell/HPE support, so it works best for redundant setups.
Also, the IPMI specification is being replaced by Redfish which is much more complete, secure, normalised and presents normal usable APIs. Any mainline server from a few years ago should have Redfish alongside IPMI.
* There's recent research from Hindenburg, a short selling research firm, that exposes some shady stuff from Supermicro - but their hardware is still top notch and used by the hyperscalers. https://hindenburgresearch.com/smci/
