OEM software is proprietary and almost always crappy anyway. Luckily there are independent builds of Android (with varying degrees of customization) for lots of phones. For a good overview over which models are supported check out which phones LineageOS supports officially: https://download.lineageos.org/ https://download.lineageos.org/ (for more intensive research on a specific phone check out its XDA forum). These devices are typically updated as long as someone cares about doing it. The Nexus 5 (released in 2013) is still receiving the most current versions of Android.
