(Nationwide) Megamarket for US election reform.
The goal of this question is to provide an at a glance general guide for the next 25 years of reforms for US elections nationwide, encompassing both primary+general elections, although some of the reforms will likely incidentally impact state elections as well (i.e. redistricting reform).
Criteria/answers largely in draft status until January 2025. Please provide suggestions, answers, edits (I will consider what answers to add but please upvote comments you like).

Background
The US electoral system has faced various calls for reform, addressing issues from voter access to campaign finance. Current reform proposals range from changing voting methods to restructuring campaign regulations. Several states have already implemented some of these reforms, while others remain under debate at state and federal levels.
Resolution Criteria
Each option will resolve YES if it is enacted into federal law or implemented nationwide (either through federal legislation or state-by-state adoption reaching all 50 states) by January 1, 2050. Early YES resolution will be delayed until "reasonable" court challenges are exhausted. Options will resolve NO if they are not enacted/implemented nationwide by this date; in general, there won't be early NO resolutions (including those passing but struck down by the court).
Specific criteria:
NPVIC: Resolves YES when states totaling 270+ electoral votes have enacted and implemented the compact
Ranked-Choice/Approval Voting: Resolves YES when implemented for all federal elections nationwide
Campaign Finance Reforms: Resolves YES when federal legislation is passed and survives any immediate court challenges
Redistricting Reform: Resolves YES when all 50 states use independent commissions for congressional redistricting
Voting Access Reforms: (Early voting, Mail-in voting, etc.) Resolve YES when implemented nationwide. Need not be same length for early voting or mail-in voting. There should be no hardship-type restrictions that restrict access to early voting or mail-in voting (everyone should have access).
Shortened Campaign Season: Resolves YES when federal law limits combined primary and general election campaigns to 6 months or less
Considerations
Constitutional amendments may be required for some reforms
Supreme Court decisions could impact the viability of certain reforms; reforms must survive decisions to resolve YES.
State-level implementation may vary in approach even under federal mandates
Some reforms may be implemented through different mechanisms than currently proposed
